Bug when converting from JSON and Powershell lists to YAML since version 0.4.8

[maritnl]

When using ConvertFrom-Yaml on a powershell or JSON object of type list, the YAML output is a list of the length of each string value instead of the actual values since version 0.4.8. It was last working properly in version 0.4.7.

Install-Module powershell-yaml -MinimumVersion 0.4.8

echo "yamlList: []" > myfile.yaml

$file = Get-Content "./myfile.yaml" 

$jsonlist = '[
    "item1",
    "item2"
]'

$file_json = $file | ConvertFrom-Yaml | ConvertTo-JSON -Depth 3 | ConvertFrom-Json
$file_json.yamlList = $jsonlist | ConvertFrom-Json
$file_json | ConvertTo-Yaml | Out-File "./outfile.yaml"

cat ./outfile.yaml

Expected output: (correct in version 0.4.7 and earlier)

yamlList:
- item1
- item2

Actual output: (since version 0.4.8)

yamlList:
- Length: 5
- Length: 5

Looking into it

For what it is worth. I have reproduced the error as well.

I as well. Looking into it.

Proposed a pr here:

• Pass non mapping to base serializer #186

I would like to add more test cases that attempt to trigger as many edge cases as possible before I merge it, but it does fix the test case in this issue. You can give it a shot my checking out the proposed branch and in a new powershell session, you can import the powershell-yaml.psd1 using its full path.
