Would MONGODB_REALM_BASE_URL be addressed as part of the other ticket https://jira.mongodb.org/browse/CLOUDP-282804? I'm assuming that would be relevant to run in CI right?

@maastha
Not sure, I removed it in 3de4c42 as I thought the changes made to appservices would address it. Should I add it back in?

I think t's okay to do that in a separate PR if you want (or in the other ticket I mentioned),

edit: would just make sure to capture this in the ticket
