I've mongodumped a very small database (2 collections, <500 documents total) from an Atlas cluster database, and want to restore it in another database on the same cluster. mongorestore doesn't output anything apparently indefinitely, and when I Ctrl+C, it finally fails, but without any actionable error message.

$ mongodump --uri $MONGO_PROD_READONLY --archive=dbrepl.mongodump$ mongodump --uri $MONGO_PROD_READONLY --archive=dbrepl.mongodump2020-05-11T18:52:21.758-0700 writing mydb.users to archive 'dbrepl.mongodump'2020-05-11T18:52:22.141-0700 writing mydb.posts to archive 'dbrepl.mongodump'2020-05-11T18:52:22.294-0700 done dumping mydb.users (384 documents)2020-05-11T18:52:22.367-0700 done dumping mydb.posts (59 documents)$ mongorestore --uri $MONGO_DEV --archive=dbrepl.mongodump2020-05-11T19:11:35.050-0700 preparing collections to restore from2020-05-11T19:11:35.114-0700 finished restoring mydb.users (0 documents, 0 failures)

frozen again

Without the `–archive` option, mongorestore does display this error message:

$ mongorestore --uri $MONGO_DEV

Failed: mydb.users: error reading database: (AtlasError) user is not allowed to do action [listCollections] on [mydb.]

The $MONGO_DEV referst to a different database, mydb-dev. I'm not sure why mongorestore wants to listCollections on mydb.
