I’ve been trying to get my project started in Unity Cloud Build to enjoy the benefits of continuous automatic builds. So far off to a rough start for this service since I’m seeing more trouble than just building locally. I’ve seen only a few other related posts to this issue with still a pending task to resolve.
This is a Stackoverflow post similar to a supposed fix to this issue:

Here’s a partial output of my log. Will have to turn off cloud build until this resolved.
