Azure DevOps Npm Authenticate Task Endpoint-CodePudding

I am currently trying to run the 'npmAuthenticate' task within my Azure DevOps pipeline but seem to be running into an issue when the 'customEndpoint' is a set varaible. It appears to work just fine if I pass the same Service Connection Name in as a parameter but not when setting as a variable else where in the pipeline.

Broken:

      jobs:
      - job: Create_Files
        displayName: Create Files
        steps:
        - task: Bash@3
          displayName: Setting npm endpoint
          inputs:
            targetType: 'inline'
            script: |
              echo "##vso[task.setvariable variable=npm_endpoint]ExampleEndpointName"
        - task: Bash@3
          displayName: Debugging step to print variable
          inputs:
            targetType: 'inline'
            script: |
              echo "Printing npm endpoint - $(npm_endpoint)"
        - task: npmAuthenticate@0
          inputs:
            workingFile: '${{ parameters.npmc_file }}'
            customEndpoint: '$(npm_endpoint)'

When I try to run this I get the following error within Azure DevOps:

Encountered error(s) while parsing pipeline YAML: Job Create_Files: Step input customEndpoint references service connection $(npm_endpoint) which could not be found. The service connection does not exist or has not been authorized for use. For authorization details, refer to

CodePudding user response：

You are setting your variable like this echo "##vso[task.setvariable variable=npm_endpoint]ExampleEndpointName" and it will "get processed during runtime".

But you are trying to use that variable like this '$(npm_endpoint)' which will "get processed during runtime before a task runs".

You are trying to use the variable before it is set.
