Based on the information provided, it seems like there might be an issue with the configuration of your Proxmox Backup Server widget. The error message "API Error: The string did not match the expected pattern" suggests that there might be a problem with the URL or the credentials provided.

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

1. Check the URL: Ensure that the URL in the widget configuration does not end with a trailing slash, as per the troubleshooting guide. It should be https://192.168.2.44:8007 without a trailing slash.

2. Verify Credentials: Make sure that the username and password fields are correctly set. The username should be in the format user@pbs!tokenid and the password should be the secret associated with the API token.

3. API Token: Confirm that the API token has been created correctly in Proxmox Backup Server and has the necessary permissions.

4. Network Access: Verify that the server where Homepage is running can access the Proxmox Backup Server on the specified IP and port.

5. Browser Console: Check the browser console for any additional error messages that might give you more insight into the issue.

6. Homepage Logs: Since you are running Homepage from the source, check the logs generated by the application for any error messages related to the widget.

7. API Response: You can also try to access the Proxmox Backup Server API directly using curl or another tool to ensure that the API is responding correctly and that the credentials are working.

If you continue to experience issues, please provide more detailed logs or error messages, which could help in diagnosing the problem further.

I am having the same exact issue. I have spent all day trying to configure the PBS widget and all my configs are correct but I get an error on the homepage side: "Something went wrong. TypeError: Cannot read properties of undefined (reading 'used')" (it is a very long error but I shortened it).

Can someone please help?

Thanks

I had to give more permissions to my user on the PBS then on the VE machines..... i gave the PBS admin role and it worked fine after that

could you elaborate a bit more on that? I have tried everything: giving admin both on api and user, recreating user and api multiple times etc etc ....

No need to elevate the role to Admin. Correct solution is here
