It looks like #6202 did not fix it. The same warnings are still there.

Scratch that. It looks like the script only pulls the nightly-master, and ignores the main. I pulled manually, and I am re-running the nightly test script.

Looks like the overnight documentation build is OK now (went from 4 warnings to no warnings).
