Task name

FileTransform

2.244.1

Issue Description

I use file transform to update some settings in my appSettings.json file with the following snippet:

- task: FileTransform@2
  displayName: 'Update host.json with production configuration for GitHubProcessor'
  inputs:
    folderPath: '$(System.DefaultWorkingDirectory)/SOME_PATH/Publish/'
    jsonTargetFiles: host.json

When the pipeline executes, I can see the following:

Starting: Update host.json with production configuration for GitHubProcessor
==============================================================================
Task         : File transform
Description  : Replace tokens with variable values in XML or JSON configuration files

As you can see, it works, but is also shows an error:

Hi @eddynaka, can you please the share me the repro steps?

  1. Create a build pipeline that has a json file with properties, let's say KeyA = ValueA, KeyB = ValueB
  2. Add a task to transform KeyA value to ValueAA and KeyB value to ValueBB
  3. Upload as artifact so you can validate the transformation
  4. Run

If you run the steps above, you will see that the artifacts will have the modified json file as expected, but you will also see errors in your pipeline regarding the replacement.
