Setting pipeline variable contains extraneous double or single quote

Question

I have the following command to set a BASE_URL variable in Azure DevOps yaml:

- script: |
    echo "##vso[task.setvariable variable=BASE_URL;]$(PROD-CONTAINER-URL)"
  condition: and(succeeded(), eq(variables['Build.SourceBranchName'], 'master'))

However whenever I echo the variable then it looks like this:

https://google.com"

If I replace it with a single quote or put the $(PROD-CONTAINER-URL) inside or outside the quotes then the problem still persists. How can I get around this and what causes it?

Answer 1

Just as in kap's answer, I saw the same behavior this week and resolved by turning off bash debugging around the variable output lines, for example:

set +x
echo "##vso[task.setvariable variable=BASE_URL;]$(PROD-CONTAINER-URL)"
set -x
