WARN: Set property error

After making changes to customised code I started to receive below error. I made the changes on 15/11.
I have compared the files that I have changed to previous files and cannot spot the issue where I have the unexpected character '"'.
Can someone perhaps assist and advise which document I need to look at based on the error below.
The help is greatly appreciated.
