buf generation issue

[solsw]

As Julien asked in Discord:
I have

• created new virtual Ubuntu Server 24.04 under Azure;

• installed go;

• installed ignite (curl https://get.ignite.com/cli! | bash);

• run 'ignite scaffold chain example';

• got:

   ERROR 

  Failed to generate openapi spec /home/osubachev/go/pkg/mod/github.com/cosmos/ibc-go/v10@v10.2.0/proto, probally you

• restarted virtual machine;

• removed downloaded ignite from /usr/local/bin/;

• downloaded the latest commit from julien/fix-gen:
  git clone https://github.com/ignite/cli.git --branch julien/fix-gen --single-branch --depth 1

• compiled and installed ignite (make install), now ignite is in $HOME/go/bin/;

• run 'ignite scaffold chain example';

• got exactly the same error.

ignite v28 works OK.

#4780 and some refactors done in #4779 were supposed to help.

Can you try https://github.com/ignite/cli/releases/tag/v29.3.0?

[solsw]

I have

• created new virtual Ubuntu Server 22.04 under Azure;

• installed go;

• installed ts-proto (npm install -g ts-proto),
  protoc-gen-ts_proto is in /usr/local/bin;

• downloaded the latest commit from 'main' branch:
  git clone https://github.com/ignite/cli.git --branch main --single-branch --depth 1

• compiled and installed ignite (make install);
  ignite version
  Ignite CLI version: v29.3.0-dev
  Ignite CLI build date: 2025-08-12T09:58:06Z
  Ignite CLI source hash: 6f451ee
  ...

• run 'ignite scaffold chain example';

• got the same error:

   ERROR 

  Error while running command go tool github.com/bufbuild/buf/cmd/buf dep update /home/osubachev/cosmos/example:
  Failure: permission_denied: 403 Forbidden : exit status 1.

It seems that ignite does not use protoc-gen-ts_proto.

Weird, let me investigate more...

Just installed Ignite v29.3.0 (curl https://get.ignite.com/cli! | bash).
The same error.

Once it was the same error as the last week one:

 ERROR 

Failed to generate openapi spec /home/osubachev/go/pkg/mod/github.com/cosmos/ibc-go/v10@v10.2.0/proto, probably you

gateway/v2/protoc-gen-openapiv2: signal: killed : exit status 1.

but on another file: applications/transfer/v1/token.proto,
last week it was core/connection/v1/genesis.proto.

Sometimes it only simply writes:
Killed

I have been able to reproduce: https://github.com/evstack/ev-abci/actions/runs/17066791863/job/48385758874?pr=203.
I'll check and release a fix ASAP.
