Password to my mongodb is nothing, and username is root. The port is not exposed outside of localhost

the error is:

I can see multiple issues here

1. Not having a password is bad practice and should be avoided. Always set a password, so that you have some protection agains people accessing the database.
   • This is also the main cause of the issue, as it seems that the password can't be null/empty
2. Don't use root. This user is only meant for you (the administrator) and shouldn't be used by plugins at all. Reason behind this is, that root can access all databases, so a malicious plugin could abuse this, or someone could take advantage of this.
   Always create a separate user (with password) that only has access to specific databases. This reduces the risk of someone harming your database a lot.

Fixed this by changing the user, thanks.
