GitVersion: [Bug] Unexpected token i in JSON at position 1

Describe the bug Azure DevOps task fails with error Unexpected token i in JSON at position 1 even though GitVersion seems to complete successfully. Tried running it locally without an issue and it works flawlessly for other repositories. It also used to work for this repository as well.

Expected Behavior

Should work.

Actual Behavior

Task fails after saying “Done writing” with error Unexpected token i in JSON at position 1. Checked the JSON just before the message and it’s valid JSON.

Possible Fix

Steps to Reproduce

To be honest I don’t know how to reproduce it, since this happens only on a specific repository. Works on other repositories. I also tried running GitVersion locally on the same repository andit works:

  INFO [01/27/21 14:46:56:87] Done writing

C:\Users\X\Documents\code\projects>echo %errorlevel%
0

Context

All of a sudden I can’t run that specific pipeline anymore since it used to work before.

Your Environment

Azure Devops, self host agents or Azure, same issue. Also for other repositories GitVersion works well on the same agents.

This issue occurs for me if I add the showConfig flag like this:

- task: gitversion/execute@0
  displayName: Determine Version
  inputs:
    additionalArguments: '/showConfig'

without that argument it works.

I’ve encountered the same problem in Azure DevOps using the GitTools extension.

A commit contained the { character, which tripped up GitVersion.

As a temporary workaround, I tried to follow the solution posted by @TomaszWegrzyn - however, version 5.6.3, not 5.6.4 seemed to do the job in my case. 🤔
