+
+I've investigated the ArgoCD deployment failure for the \`2-broken-apps\` application and identified **two critical issues** in the source repository's Kubernetes manifest file.
+
+### Issue 1: Invalid apiVersion ❌
+
+**Location:** Line 178 in \`apps/broken-aks-store-all-in-one.yaml\`
+
+\`\`\`yaml
+apiVersion: apps/v
+kind: Deployment
+metadata:
+  name: order-service
+\`\`\`
+
+**Problem:** The \`apiVersion\` field is incomplete. It should be \`apps/v1\` but is only \`apps/v\`.
+
+**Impact:** This causes ArgoCD sync to fail because Kubernetes cannot recognize this as a valid resource definition.
+
+---
+
+### Issue 2: Incorrect Container Image Name ❌
+
+**Location:** Line 475 in \`apps/broken-aks-store-all-in-one.yaml\`
+
+\`\`\`yaml
+containers:
+  - name: store-admin
+    image: ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0
+\`\`\`
+
+**Problem:** The image name has a typo: \`store-dmin\` should be \`store-admin\`.
+
+**Impact:** Even if the manifest syncs successfully, this pod will fail to start because the image doesn't exist in the container registry.
+
+---
+
+## 🔧 Remediation Recommendations
+
+### Option 1: Fix the Source Repository (Recommended)
+
+Since the application is pointing to an external repository (\`https://github.com/dcasati/argocd-notification-examples.git\`), the best solution is to fix the issues at the source:
+
+1. **Contact the repository owner** (@dcasati) or submit a pull request to fix:
+   - Line 178: Change \`apiVersion: apps/v\` to \`apiVersion: apps/v1\`
+   - Line 475: Change \`store-dmin\` to \`store-admin\`
+
+2. **Wait for ArgoCD auto-sync** (or manually trigger sync):
+   \`\`\`bash
+   argocd app sync 2-broken-apps
+   \`\`\`
+
+### Option 2: Fork and Fix
+
+If you need immediate resolution:
+
+1. **Fork the repository** to your own GitHub account or organization
+2. **Fix the two issues** mentioned above
+3. **Update the ArgoCD Application** spec in \`Act-3/argocd-test-app.yaml\`:
+   \`\`\`yaml
+   spec:
+     source:
+       repoURL: https://github.com/YOUR-ORG/argocd-notification-examples.git
+       targetRevision: main
+       path: apps
+   \`\`\`
+
+### Option 3: Local Patch (Not Recommended)
+
+Apply the resources with corrections directly to the cluster, but this will cause drift from the GitOps source.
+
+---
+
+## ✅ Verification Steps
+
+After applying the fix:
+
+1. **Check ArgoCD application status:**
+   \`\`\`bash
+   argocd app get 2-broken-apps
+   \`\`\`
+
+2. **Verify all pods are running:**
+   \`\`\`bash
+   kubectl get pods -n default
+   kubectl get deployment order-service -n default
+   kubectl get deployment store-admin -n default
+   \`\`\`
+
+3. **Check pod status and logs:**
+   \`\`\`bash
+   kubectl describe deployment order-service -n default
+   kubectl describe deployment store-admin -n default
+   kubectl logs deployment/store-admin -n default
+   \`\`\`
+
+---
+
+## 📋 Summary
+
+The deployment failure is caused by:
+1. ✗ Incomplete \`apiVersion: apps/v\` (should be \`apps/v1\`) - **Line 178**
+2. ✗ Typo in image name \`store-dmin\` (should be \`store-admin\`) - **Line 475**
+
+**Recommended Action:** Contact the repository owner or submit a PR to fix these issues in the source repository, then re-sync the ArgoCD application.`;
+
+            await github.rest.issues.createComment({
+              owner: context.repo.owner,
+              repo: context.repo.repo,
+              issue_number: parseInt('${{ github.event.inputs.issue_number }}'),
+              body: commentBody
+            });
+
+            console.log('Root cause analysis comment posted successfully!');

+# Root Cause Analysis: ArgoCD Deployment Failure (2-broken-apps)
+
+**Investigation Date:** 2026-02-03  
+**Application:** `2-broken-apps`  
+**Status:** Degraded / OutOfSync  
+**Related Issue:** #12
+
+## 🔍 Root Cause Analysis
+
+I've investigated the ArgoCD deployment failure for the `2-broken-apps` application and identified **two critical issues** in the source repository's Kubernetes manifest file.
+
+### Issue 1: Invalid apiVersion ❌
+
+**Location:** Line 178 in `apps/broken-aks-store-all-in-one.yaml` from repository `https://github.com/dcasati/argocd-notification-examples.git`
+
+```yaml
+apiVersion: apps/v
+kind: Deployment
+metadata:
+  name: order-service
+```
+
+**Problem:** The `apiVersion` field is incomplete. It should be `apps/v1` but is only `apps/v`.
+
+**Impact:** This causes ArgoCD sync to fail because Kubernetes cannot recognize this as a valid resource definition. The error message "one or more synchronization tasks are not valid" is a direct result of this malformed apiVersion.
+
+---
+
+### Issue 2: Incorrect Container Image Name ❌
+
+**Location:** Line 475 in `apps/broken-aks-store-all-in-one.yaml`
+
+```yaml
+containers:
+  - name: store-admin
+    image: ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0
+```
+
+**Problem:** The image name has a typo: `store-dmin` should be `store-admin`.
+
+**Impact:** Even if the manifest syncs successfully after fixing Issue 1, this pod will fail to start because the image `store-dmin:2.1.0` doesn't exist in the container registry. Only `store-admin:2.1.0` exists.
+
+---
+
+## 🔧 Remediation Recommendations
+
+### Option 1: Fix the Source Repository (Recommended) ⭐
+
+Since the application is pointing to an external repository (`https://github.com/dcasati/argocd-notification-examples.git`), the best solution is to fix the issues at the source:
+
+1. **Contact the repository owner** (@dcasati) or submit a pull request to fix:
+   - **Line 178:** Change `apiVersion: apps/v` to `apiVersion: apps/v1`
+   - **Line 475:** Change `ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0` to `ghcr.io/azure-samples/aks-store-demo/store-admin:2.1.0`
+
+2. **Wait for ArgoCD auto-sync** (configured with `automated: true`) or manually trigger sync:
+   ```bash
+   argocd app sync 2-broken-apps
+   ```
+
+3. **Verify the deployment** using the verification steps below.
+
+**Advantages:**
+- Fixes the root cause
+- Maintains GitOps principles
+- Benefits other users of the repository
+
+---
+
+### Option 2: Fork and Fix 🍴
+
+If you need immediate resolution and cannot wait for the upstream fix:
+
+1. **Fork the repository** to your own GitHub account or organization:
+   ```bash
+   # Via GitHub UI or:
+   gh repo fork dcasati/argocd-notification-examples --clone=false
+   ```
+
+2. **Clone your fork and fix the issues:**
+   ```bash
+   git clone https://github.com/YOUR-ORG/argocd-notification-examples.git
+   cd argocd-notification-examples
+
+   # Fix Issue 1
+   sed -i 's/apiVersion: apps\/v$/apiVersion: apps\/v1/' apps/broken-aks-store-all-in-one.yaml
+
+   # Fix Issue 2
+   sed -i 's/store-dmin:2.1.0/store-admin:2.1.0/' apps/broken-aks-store-all-in-one.yaml
+
+   git commit -am "Fix apiVersion and image name typos"
+   git push
+   ```
+
+3. **Update the ArgoCD Application** spec in `Act-3/argocd-test-app.yaml`:
+   ```yaml
+   spec:
+     source:
+       repoURL: https://github.com/YOUR-ORG/argocd-notification-examples.git
+       targetRevision: main
+       path: apps
+   ```
+
+4. **Apply the updated ArgoCD Application:**
+   ```bash
+   kubectl apply -f Act-3/argocd-test-app.yaml
+   ```
+
+**Advantages:**
+- Immediate resolution
+- Full control over the manifests
+- Can be used until upstream is fixed
+
+---
+
+### Option 3: Local Patch (Not Recommended) ⚠️
+
+Apply the resources with corrections directly to the cluster:
+
+```bash
+# Download and fix the manifest
+curl -o /tmp/fixed-app.yaml https://raw.githubusercontent.com/dcasati/argocd-notification-examples/main/apps/broken-aks-store-all-in-one.yaml
+
+# Edit /tmp/fixed-app.yaml to fix both issues, then apply:
+kubectl apply -f /tmp/fixed-app.yaml -n default
+```
+
+**Disadvantages:**
+- Creates drift from GitOps source
+- ArgoCD will constantly try to sync back to the broken state
+- Not a sustainable solution
+
+---
+
+## ✅ Verification Steps
+
+After applying the fix (via Option 1 or 2):
+
+### 1. Check ArgoCD Application Status
+
+```bash
+# Check overall application health
+argocd app get 2-broken-apps
+
+# Expected output should show:
+# - Health Status: Healthy
+# - Sync Status: Synced
+```
+
+### 2. Verify All Pods Are Running
+
+```bash
+# Check all pods in the namespace
+kubectl get pods -n default
+
+# Check specific deployments
+kubectl get deployment order-service -n default
+kubectl get deployment store-admin -n default
+
+# Expected: All deployments should show READY 1/1
+```
+
+### 3. Verify Deployments in Detail
+
+```bash
+# Check order-service deployment
+kubectl describe deployment order-service -n default
+
+# Check store-admin deployment  
+kubectl describe deployment store-admin -n default
+
+# Verify the image name is correct
+kubectl get deployment store-admin -n default -o jsonpath='{.spec.template.spec.containers[0].image}'
+# Expected: ghcr.io/azure-samples/aks-store-demo/store-admin:2.1.0
+```
+
+### 4. Check Pod Logs (if issues persist)
+
+```bash
+# Check order-service logs
+kubectl logs deployment/order-service -n default --tail=50
+
+# Check store-admin logs
+kubectl logs deployment/store-admin -n default --tail=50
+```
+
+### 5. Monitor ArgoCD Sync
+
+```bash
+# Watch the sync progress
+argocd app sync 2-broken-apps --watch
+
+# Check recent sync history
+argocd app history 2-broken-apps
+```
+
+---
+
+## 📋 Summary
+
+The deployment failure is caused by **two distinct issues** in the external repository's manifest file:
+
+| Issue | Location | Current Value | Expected Value |
+|-------|----------|---------------|----------------|
+| **Invalid apiVersion** | Line 178 | `apiVersion: apps/v` | `apiVersion: apps/v1` |
+| **Typo in Image Name** | Line 475 | `store-dmin:2.1.0` | `store-admin:2.1.0` |
+
+### Recommended Action
+
+**Primary:** Contact the repository owner (@dcasati) or submit a PR to https://github.com/dcasati/argocd-notification-examples.git fixing both issues, then re-sync the ArgoCD application.
+
+**Alternative:** Fork the repository, fix the issues, and update your ArgoCD application to point to your fork for immediate resolution.
