Error: failed: error connecting to db server
The server returned an error on SASL authentication step. The specific error is “bson field ‘saslcontinue.mechanism’ is an unknown field”.
This error usually occurs when there is a problem with the authentication process while connecting to a database server.
Possible Causes:
- Incorrect authentication credentials.
- Mismatch between the server’s expected authentication mechanism and the one provided.
- An issue with the MongoDB configuration.
Solutions:
To resolve this error, you can try the following solutions:
- Verify the authentication credentials: Make sure that the credentials (username and password) used for connecting to the database server are correct. Double-check for any typos or misspellings.
- Check the authentication mechanism: Determine the authentication mechanism expected by the database server and ensure that you are using the correct one. Some common authentication mechanisms are SCRAM-SHA-1, MONGODB-CR, and PLAIN.
- Review the MongoDB configuration: Examine the MongoDB server’s configuration files (such as mongod.conf) to ensure that the authentication mechanism is properly configured. You may need to make changes to the configuration to align it with your authentication requirements.
- Restart the MongoDB server: If you have made any changes to the configuration, restart the MongoDB server to apply the changes and see if the error still persists.
Example:
Here is an example of a MongoDB connection string using SCRAM-SHA-1 authentication mechanism:
mongoose.connect('mongodb://username:password@localhost:27017/database?authMechanism=SCRAM-SHA-1');
Ensure that you replace username, password, and database with your actual credentials and database name.
