Azure DevOps API release definition - azure-devops

Question

I'm getting the following error when trying to copy a release template from a different project
"VS402982: A retention policy is not set for the stage ‘PROJECT-ENV’. Retention policies at the release pipeline level are deprecated.
{

},
copying from current build.

Answer 1

Your JSON is not valid. You'll need to ensure all the nested values are expanded correctly. For example:
"retentionPolicy": "#{daysToKeep=30; releasesToKeep=3; retainBuild=True}",
should be
"retentionPolicy": {
"daysToKeep" : 30,
"releasesToKeep": 3,
"retainBuild": true
},
If you're using PowerShell to create this JSON then ensure to specify the Depth parameter so it expands each value correctly.
