It's not an ERROR and doesn't break the build.
It's more of a warning/info but when running it is shown with [ERROR] which
can be misleading when looking for build errors.
I actually get a few more if I clean the repo like a new clone with: `git
clean -dxf`
(Warning, this will wipe out your notebooks and config files)
