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

[manuel-lkmx]

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.
