With no code changes all our cosmos DB tests started failing sometime in the last week with:

thanks for the update @jhendrixMSFT, we are going to release 1.31 today with an unideal fix (ignore 500s) but it'll unblock users

@katbyte RP has fixed this and I confirmed it's working now. Please let me know if you still have issues.
