      It's worth noting that this passes locally using AWS drivers-evergreen-setup.

      The test likely needs the following guard:

      parsedOpts := options.Client().ApplyURI(rawURI)
if parsedOpts.Auth == nil || parsedOpts.Auth.Username == "" {
    t.Skip("no inline credentials in MONGODB_URI; scenario requires AWS SDK default provider")
}
