Error Dialog vs. Custom Error

Help
1

I build a flow: Event Hook Trigger → Run Script

1.) If there is an error I throw the error: throw new Error(“ERROR MESSAGE“);

If I’m an admin, I see the error dialog with the text “ERROR MESSAGE“.
If I’m not the admin, the text is a generic text…!?

Is it possible to display the same error text regardless of authorisation?

2.) Extension “custom error handler”

I tried to resolve this issue using the “custom error handler” extension. I’m using Directus version 11.1.0. Instead of displaying an error dialog, a red error notification appears in the bottom right corner.

How can I display an error dialog instead of the notification?

This error behavior is very strange…

Sounds like an issue with the Bulk Import api, would you mind opening an issue in GitHub so the core team can review: https://directus.io/docs/community/reporting-and-support/bug-reporting

Thank you! Appreciate your detailed descriptions and testing.

You can also add a link to this discussion to the issue. :slight_smile:

Use the Throw Error operation on the false path to customize the error message. eg:

OK!

Test as no-admin:

“ERROR MESSAGE” is not displayed…

Ok it took a couple of reads to understand the issue you are facing. Let me ensure I understand:

  • Create Flow with filter(blocking) trigger on item create
  • Create item in Data Studio with plus(+) icon on the collection
    • Custom flow error message shown for both admin & non-admin – correct?
  • Bulk Import items in Data Studio
    • Custom flow error message only shows when admin - non-admin gets generic error Is this correct?​

If it is the second issue, eg the Bulk Import is not returning the custom message, then please open an issue: https://directus.io/docs/community/reporting-and-support/bug-reporting

The error dialog is only displayed if an item is created manually. A red notification is displayed during import.

  • Create Flow with filter(blocking) trigger on item create
    → Correct

  • Create item in Data Studio with plus(+) icon on the collection

    • Custom flow error message shown for both admin & non-admin – correct?
      → Correct!

  • Bulk Import items in Data Studio

    • Custom flow error message only shows when admin - non-admin gets generic error Is this correct?​
      → No… Bulk import shows a red notification instead of an error dialog
