json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 17 column 1 (char 476)

My actual error was when started bench i got some syntax error but i got the solution for it which needed to run bench update --requirements but im getting this error when i run the command. Please guide me through this Hope Anyone of u can help me with this.

did you change anything recently in the common_site_config.json - it is available in the sites folder, check the property on line 17. the code is expecting the key in double quotes.

I checked the file and i didn’t change anything, All the keys are in double qoutes too.

When run bench start im getting the following error.
