Hi @fantq1005! I'm Dosu and I’m helping the dify-official-plugins team.

This error happens when the plugin daemon returns data in a format that doesn't match what the Dify frontend expects—usually because the main Dify app and the plugin daemon are running different versions. The system expects a dictionary with specific fields (like list and total), but sometimes gets a raw list or a mismatched structure, which triggers the parsing failure. Keeping both the main Dify application and the plugin daemon on the same version resolves this issue, and recent updates in the codebase specifically address version alignment to prevent these errors [source] [source].

If you're on Dify Cloud, this is likely a temporary backend issue or an in-progress update. If the problem persists, it may help to check for any ongoing platform updates or reach out to the Dify Cloud team to confirm that all components are running compatible versions.

To reply, just mention @dosu.
