Error: There was an error building the project. Please read the logs for details

Bug description

After successfully build on the license step fails saying "Error: There was an error building the project. Please read the logs for details."

How to reproduce

Configure the step

      # Build
      - name: Build project
        uses: game-ci/unity-builder@v3
        env:
          UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }}
        with:
          unityVersion: ${{ matrix.unityVersion }}
          targetPlatform: ${{ matrix.targetPlatform }}

Setup the secret variable UNITY_LICENSE
Launch the build action manually
Linux/Mac/Windws build will fail

Step configured https://github.com/humbertodias/unity-mugen/blob/main/.github/workflows/release.yml

Expected behavior

Should pass through without any problem, because the activation was completed.

Changing to "/github/workspace/_activate-license~" directory.
/github/workspace/_activate-license~ /github/workspace
Requesting activation (personal license)
Activation complete.

Another weird behavior is related to WebGL version that works well However, linux, windows and mac fails.

Before v3, we didn't look for actual errors, we only considered Unity's exit code.

In your case, we can see that Unity build succeeded:

2023-10-13T14:04:41.5215929Z Build succeeded!

but have a look at this here:

The pipeline failed due to 4 errors during the build. Yes Unity managed to create a build, but a few things went wrong.

Based on action implementation, this is handled here.

As you can see, if it finds Errors: (and it did find it in your case), then the workflow is marked as failed even if there was a build produced.

v2 to v3 of the actions added this error checking in logs. There are active discussions about this possible breaking change and how we should actually improve this.

This is actually a proposal that will most likely help with that: https://github.com/game-ci/unity-builder/pull/576

Searching in the logs you linked, I found this:

In other words, something went wrong trying to build with these lighting settings (if I understand correctly). Here's a very similar issue posted on our discord server.
