Issue Summary

We need to provide a clear message for invalid input when saving Features, so the user knows what is wrong and can fix it. For customers using a large description, for example, it is not easy to pinpoint the cause.

Steps to Reproduce

1. Create a Feature
2. Add the following string to the description:

   ScriptCode.js?onload= event
   

3. Try to save the Feature
4. The following error message is shown:

   Invalid user input
   

Expected Results

A clear message that would allow the user to understand the issue and fix the problem.

Actual Results

Not clear error message: "Invalid user input".
(text size, text content, which field)

Workaround

None available besides fix the input.
