Unable to run builds - Exception thrown during config processing: UNAVAILABLE

[tpiecora]

Builds are failing with this error:
Exception thrown during config processing: UNAVAILABLE

CLI tool also throws that error when trying to validate a config

I had the same problem and I changed the version of my config.yml file from 2 to 2.1 and works.

2.1 Config and Build Processing

This is a general thread for feedback on the new 2.1 features of config and the new build processing system. If you don’t yet have the build processing setting on your projects (under Advanced on the project’s Settings page) you will soon as we roll it out to more and more organizations.

At the time this was reported we had a hiccup in our database connectivity. That was restored, and we remediated the underlying cause. The change to 2.1 config probably was not necessary to fix, but triggering a new build with a fresh commit would have caused your jobs to work once the incident was over. We are looking at ways to better communicate that when there’s a config processing error a rerun won’t fix whatever the underlying cause was, and you need to push a fresh commit through.
