Error message: The type 'MappingToken' was expected.

I'm trying to use this GitHub Action inside a composite action, which is available at https://github.com/microsoft/nubesgen-actions/blob/test-azure-spring-cloud-deployment/gitops-deploy-to-spring-cloud-java/action.yml

When running it, I get an error saying "The type 'MappingToken' was expected." - could you help me understand what this is? Here is the full log:

As described in this link https://stackoverflow.com/questions/44327773/mapping-values-are-not-allowed-in-this-context, the error may be casued by yaml format. Would you please check the line 33 and try to remove the unexpected spaces in front of uses and with. I think the format may be like that:

    - name: Deploy to Azure Spring Cloud
      uses: azure/spring-cloud-deploy@v1
      with:
        action: deploy
        service-name: ${{ env.SPRING_CLOUD_SERVICE_NAME }}
        app-name: ${{ env.APPLICATION_CAF_NAME }}
        use-staging-deployment: ${{ inputs.use_staging_deployment }}
        package: "*.[j,w]ar"

I hope this could help you !

Oh I feel stupid ! I haven’t tested this yet, but it’s clearly the issue, so I’m closing this. Thank you.
