Problem Statement/Rationale

We have noticed a few tenant upgrades that failed to restore certain namespaces with ending newline characters. Newline characters are valid and should be able to be restored. Mongodump does recognize these collections and they are dumped as necessary but not the restore.

In the logs below, mongorestore thinks it is done but when comparing to the mongodump logs, we see that the collection ending with newlines were not restored and no logs indicate any attempt at restoring.

Example logs on atlas prod

Mongodump log: https://cloud.mongodb.com/admin/nds/serverlessDowngradeToFree/67b76767bbbab53a95647858/logs?logType=mongodump

Mongorestore log:
https://cloud.mongodb.com/admin/nds/serverlessDowngradeToFree/67b76767bbbab53a95647858/logs?logType=mongorestore

Steps to Reproduce

Create a collection that ends with a newline character and it should not be restored but it is dumped

Expected Results

All dumped db and collections to be restored

Actual Results

Collections with ending newline characters are not being restored

Additional Notes

This is blocking the completing of forced serverless to free migrations and could potentially become blocker for serverless to dedicated migrations
