BUG - handle http 404's in control property editor

[longieirl]

Description

Closing VSCode causes errors if changes are done in CPE.

Steps to Reproduce

1. Create ADP in VSCode
2. Open CPE
3. Close VSCode which probably also closes the server on which CPE is running
4. Do a change in CPE and save it

Expected results

In this instance, the server is no longer running and CPE should handle known exceptions i.e http 404 and give the user a better error message.

Actual results

Error is shown to the user showing exception around fetching service.
