If you found this type of warning “The script tag contains invalid JSON that cannot be parsed” in your website and that warning occurs If you have added the invalid JSON in your code and if you are not adding proper JSON code then you will get this type of warning so make sure you enter the valid JSON
For Example:
In this Example, we will show you an example code of invalid JSON code in Analytic and you can see there is an extra comma like below the screenshot and because of that only warning is appearing

Once you remove the extra comma in code then your JSON Code is valid like below the screenshot.

That’s it for this tutorial!
We hope it helped you. If you have any feedback or questions, then please share them in the comments section below.
Also, you can use any JSON validator, I did next when faced it: https://hinty.io/devforth/fix-the-script-tag-contains-invalid-json-that-cannot-be-parsed/
