What are you seeing?

I have an Azure DevOps pipeline that does the following steps:

steps:
- checkout: self
  fetchDepth: 0

- task: gitversion/setup@3
  displayName: 'setup GitVersion'
  inputs:
    versionSpec: 5.x

- task: gitversion/execute@3
  displayName: 'execute GitVersion'
  inputs:
    updateAssemblyInfo: true

It fails on execute GitVersion with the following:

Starting: execute GitVersion

##[error]GitVersion output is not valid JSON

I have tried with a custom GitVersion.yml config file that I know is valid as works on another project with the same result, so I'm using the default config for testing.

What is expected?

It should not error out with invalid JSON error.

Steps to Reproduce

• Create new pipeline in Azure DevOps
• Add GitTools extensions
• Add gitversion/setup step
• Add gitversion/execute step
• Run pipeline
