Printing template parameters in azure devops template

Question

Is there a task or command that I can use to output all the parameters variable in a Azure DevOps template when the pipeline is run?

I would like the first task in the pipeline to print all parameters, that would help to spot mistakes.

Any suggestions

At the moment there is no way to display template parameters using single command, so your only option is printing them one be one like this:

- script: |
    echo 'vmImage - ${{ parameters.vmImage }}'
    echo 'anotherRuntimeParameter - ${{ parameters.anotherRuntimeParameter }}'

I was also faced with this requirement and found the following solution:

    - script: |    
       echo "${{ convertToJson(parameters) }}"
