Package.json is not a valid JSON file

Hi. Please help, My application has been running perfectly fine but when I tried running it today, I got an error saying "package.json is not a valid JSON file - "Unexpected token ".

please help me fix it. Thanks

The error says it all, your package.json is invalid JSON - open the file in Visual Studio Code or any other text editor and check what’s invalid. If you are using source control you should definitely check what and when changed.
