@dosubot[bot] commented on GitHub (Jul 21, 2025):

The error happens because the dayjs 'relativeTime' plugin isn't initialized in the MCP frontend code, so calling .fromNow() fails. To fix this, import and extend the plugin before any .fromNow() usage. You can do this either globally (recommended for consistency) or locally in the MCP-related files.

Example for local fix (add at the top of any MCP component or hook that uses .fromNow()):

import dayjs from 'dayjs'
import relativeTime from 'dayjs/plugin/relativeTime'
dayjs.extend(relativeTime)

This should be done before any code that calls dayjs().fromNow() or similar. For a more robust solution, consider initializing the plugin in a global setup file or your main app entry point so all components have access to it without repeating the import/extend logic. This approach is used in other Dify frontend components and avoids similar bugs elsewhere in the app.

More details and examples can be found in other components that use dayjs with 'relativeTime' correctly, such as the app publisher and members page components (example).

To reply, just mention @dosu.
