Backend validation errors are not displayed in Toolkit forms (Database section) #386

Description

In the Toolkit module, when adding or updating forms—especially within the Database section—backend validation errors are correctly triggered and returned, but they are not handled or displayed on the frontend.

This results in failed form submissions with no visible feedback to the user.

Current Behavior

• Open a form in the Toolkit module (e.g. add or update action in the Database section).
• Submit the form without providing required or mandatory fields.
• Backend validation fails and returns an error response.

Result

• The request fails on the backend
• No validation errors or messages are shown on the frontend
• User receives no indication of what went wrong

Expected Behavior

• Backend validation errors should be properly captured on the frontend
• Relevant error messages should be displayed clearly to the user
