UI Error when filtering workflows by clicking on a tag: "Parsed filter does not fit the schema"

[gexin920]

Bug Description

Error fetching workflows
Parsed filter does not fit the schema

Describe the bug: When attempting to filter workflows by clicking on a tag (chip) in the dashboard, the application throws a toast error: Error fetching workflows: Parsed filter does not fit the schema. This suggests a mismatch between the filter payload sent by the frontend and the validation schema expected by the backend API.

To Reproduce

To Reproduce:

Navigate to the Workflows list (/home/workflows).

Identify a workflow that has tags assigned (e.g., "orders").

Click on the tag chip displayed on the workflow card.

Result: The UI shows a loading state briefly, then fails with the toast error: Parsed filter does not fit the schema.

The list is not filtered, or enters a broken state.

Expected behavior

Expected behavior: Clicking a tag should strictly filter the workflow list to show only items containing that tag, matching the backend schema requirements.

Debug Info

Additional Context:

This appears to be a backend validation error (likely Zod or similar) rejecting the query parameters generated by the frontend.

I have tried clearing browser cache/cookies to rule out frontend asset caching issues, but the issue persists.
