Test Impact (Run only Impacted tests) and Code Coverage data collector will not work.

Hello, Ajeet
I faced same error and found solution from below url as it seems due to version mismatch.
##[warning]Test Impact (Run only Impacted tests) and Code Coverage data collector will not work. · Issue #15449 · microsoft/azure-pipelines-tasks · GitHub

This is the solution.
Downgrading 17 to 16 resolved this problem for me as well. For reference the relevant build step:
- task: VisualStudioTestPlatformInstaller@1
      inputs:
          packageFeedSelector: 'nugetOrg'
          versionSelector: 'specificVersion'
          testPlatformVersion: '16.11.0'
