Error using assignment file with comments

[tiwilson7]

Problem

We recently ran into an error when we added comments to our assignment files.

It seems that ConvertFrom-Json in older powershell versions do not support json with comments but newer versions do support it.

Broken: 5.1
Working: 7.1.5

Solution

This task is incredibly helpful! It would be great if the powershell version could be updated so that assignment would work with json with code comments. We have found adding comments is very helpful in maintaining the blueprint.

It seems like this could be a quick fix to task.json

Workaround

We are currently using this inline powershell script as a workaround.

Write-Host 'The Assign Azure Blueprint task uses an old version of powershell that does not support json with comments.' 

Write-Host "Removing comments from $(blueprintAssignmentPath)"

(Get-Content '$(blueprintAssignmentPath)')  -replace '^\s*//.*' | Out-File '$(blueprintAssignmentPath)'
