Error Message

The Notion Trigger node (specifically the pagedUpdatedInDatabase event) functions correctly during manual testing (Test Step), but fails immediately when the workflow is set to Active. Crucially, the "Error details" pane is completely empty, showing no status code or error message, which makes debugging impossible. Check the Executions log; the error details are missing/blank. If it fails, the UI must display the actual error returned by the Notion API (e.g., 400, 404, 500) so the user can diagnose the data issue. UI Bug: No error description, stack trace, or API response code is displayed in the error panel.

The Notion Trigger node (specifically the pagedUpdatedInDatabase event) functions correctly during manual testing (Test Step), but fails immediately when the workflow is set to Active. Crucially, the "Error details" pane is completely empty, showing no status code or error message, which makes debugging impossible.

To Reproduce

Set up a Notion Trigger node (Page Updated in Database).

Confirm the node works via "Test Step".

Activate the workflow.

The workflow fails on the first polling interval.

Check the Executions log; the error details are missing/blank.

Expected behavior

The trigger should stay active and poll for changes correctly. If it fails, the UI must display the actual error returned by the Notion API (e.g., 400, 404, 500) so the user can diagnose the data issue.

Debug Info

In Test Mode: Works fine, retrieves records.

In Active Mode: Fails instantly.

UI Bug: No error description, stack trace, or API response code is displayed in the error panel.
