WebGL build failing with no errors

[celojevic]

Hello there! I just got into adding CI/CD for my game. I was able to get a mac build successfully going. However, I'm having issues with it on the webgl platform. It keeps failing after ~45 minutes during the build step. Any help or advice would be appreciated!

Ive also attached the logs from the failed build.

And here are some screenshots from my build summary:
