I think this error have regressed - at least I am now getting the same errors again, and I also checked your result @mark-piller , and it also gives the same error again:
Invalid option item in the Select Component, make sure each option object has defined "objectId" property, otherwise the option will be skipped
A bit annoying to have these errors thrown around everywhere, even though it is not impacting my apps as such, so it would be nice to have this fixed again…

I deleted them from my test page, and now the error is gone:

I agree the error should not be there in the first place, and we will look into it, however, it still is completely harmless and easily avoidable.
Regards,
