@mwaxmonsky I suggest removing the coupler-build test from the CI test list. Could you do so in #6 ? I’m also happy to push the change directly to your PR branch if you prefer.

Thanks @alperaltuntas! I set it to only run upstream so we should be able to merge in updates as needed without too many conflicts.
