My JSON code disappeared after it was saved, how can I get it back?

If there is an error in the modified JSON code, the code will not appear in the edit box. In order to recover, there are 2 best practices:

• Always copy the working code to a text or code editor prior to changing any code. If there is a code error. Simply copy from the editor and paste it into the code box.
• Always have the UI Builder open when modifying the Group Variable code. If an error occurs and the code disappears, navigate to the UI Builder and select “Save”. The code will be recreated to the previous state prior to the code modification.
