Trying to save a field too long brings up a 500 error

[Aboullos]

Steps

• Go to "Client Scope"
• Go to "Create client scope" or go to an item details
• Fill any text input with a long text
• Click "Save"

Expected result:

• The error is handled and the notification to the users shows a message warning about the length of the text
• Http response message warns about the error

Actual result:

• Notification message unclear to user: "Could not update client scope: 'Error: Request failed with status code 500'"
• Http response message is: {"error":"unknown_error"}

This happens on lots of our forms. We need to go through the whole app and do basic validation for lengths and numerics.
