How to customize the error message displayed

Feature(s) impacted

I’m using the cloud version of forest admin
I want to override the create function of a collection to call my backend which handle the business logic
So I called the collection.overrideCreate function
But when my API sends a validation error I can’t display the response in the frontend (see screenshot)

I tried to throw a BusinessError with a custom message from the @forestadmin/datasource-toolkit package but I still get the default error message.

I saw that I could use [customizeErrorMessage]( with self hosted version.
But I don’t know how to do it with the cloud version because we don’t call createAgent

Is it possible to display a custom message ?

Observed behavior

I get the default message

Expected behavior

I can customize the error message in overrideCreate function

Hello @Quentin_Somerville1 ,

The fix is live, you should be able to see custom error messages from your agent in your browser.
