BSONError in MongoDB Compass

ghz 9months ago ⋅ 78 views

I've newly installed the MongoDB Windows Server, Mongosh and MongoDB Compass. Everytime I try to connect Compass to the my local Server, it throws the following error:

Failed to retrieve server info BSONError: Invalid UTF-8 string in BSON document

This is very strange because in mongosh the connexion works very well. I've reinstalled the three named applications two times but the problem remains.

The error message "Failed to retrieve server info BSONError: Invalid UTF-8 string in BSON document" typically indicates that MongoDB Compass is encountering an issue while trying to parse a BSON document from the MongoDB server.

Here are a few steps you can take to troubleshoot and potentially resolve the issue:

  1. Check MongoDB Server Logs: Start by checking the logs of your MongoDB server for any errors or warnings that might indicate an issue with the server configuration or operation. Look for any errors related to connections or BSON parsing.

  2. Check MongoDB Server Configuration: Make sure that your MongoDB server is configured correctly and is accessible from your local machine. Ensure that the server is running and accepting connections on the expected port (default is 27017).

  3. Update MongoDB Compass: Ensure that you are using the latest version of MongoDB Compass. Sometimes, compatibility issues between different versions of MongoDB server and Compass can cause issues. Updating to the latest version may resolve the problem.

  4. Check Network Configuration: Verify that there are no network issues or firewall rules blocking connections between MongoDB Compass and the MongoDB server. Ensure that your local machine can connect to the MongoDB server's IP address and port.

  5. Try Connecting with Different Options: In MongoDB Compass, try connecting using different connection options (e.g., using a connection string, specifying SSL options, etc.). Sometimes, adjusting connection settings can help resolve connectivity issues.

  6. Check Document Data: If possible, try to identify any specific BSON documents that might be causing the error. It's possible that there is data in the MongoDB server that is not UTF-8 encoded or contains invalid characters.

  7. Reinstall MongoDB Compass: If none of the above steps resolve the issue, try uninstalling and reinstalling MongoDB Compass. Make sure to completely remove any existing installation files and configuration settings before reinstalling.

If the issue persists after trying these steps, you may want to consider reaching out to MongoDB support or community forums for further assistance. They may be able to provide more specific guidance based on your setup and environment.
