Error reading JToken from JsonReader

Related error messages:

• The template is not valid. .github/workflows/ms.eventgrid.topics.yml (Line: 116, Col: 29): Error reading JToken from JsonReader. Path '', line 0, position 0.

Potential reasons

• The AZURE_CREDENTIALS are not configured as a single-line string, but as a multiline JSON.

  • Solution: As per the documentation please ensure that the secret is created in one line. That means using

    { "it's a me" }

    instead of

    {
      "it's a me"
    }

  • Background: If configured as a multiline object, GitHub interprets each line as a dedicated secret value. This leads to a situation where characters like { & } are treated as individual secrets - and values that are passed as JSON strings between pipeline jobs that contain these characters cannot be passed anymore (as per GitHubs default behavior). For example: {"removeDeployment": true}. Because this value isn't passed anymore, subsequently the line removeDeployment: '${{ (fromJson(needs.job_initialize_pipeline.outputs.workflowInput)).removeDeployment }}' that references it throws the error message you're seeing.
