Issue with UnityTestTask@1 - The "path" argument must be of type string. Received type undefined

[IanMoroney]

So, trying to use the example in the docs, and I get the error: The "path" argument must be of type string. Received type undefined when trying to run the task.

This is the debug output from the task:

Finishing: unitytest

According to the docs, there isn't an input called path. According to the code, unity-test.ts does refer to path and it joins it with task.json. However, in the above debug output, you can see the check path running which shows a full path to the task.json, so I don't know exactly what's going wrong here.

I assume i'm not missing any required input parameter, and my build environment is fine. If i'm missing something, can you let me know what it is?

YAML:

steps:
- task: UnityTestTask@1
  name: unitytest
  inputs:
    testMode: editMode
    unityProjectPath: $(System.DefaultWorkingDirectory)
