Postman API Fundamentals Student Expert Error

Using PATCH in workspace “Postman API Fundamentals Student Expert”, I got an
error message as follows:
“message”: “Unexpected token = in JSON at position 20”
With status code 400,
I’m suppose to have a 200 status code

Have a look at the body, and in particular what is being underlined in red.

That is not valid JSON. The equals sign should not be there.

Have a look at the following for the correct syntax.

JSON Syntax (w3schools.com)

thanks Mike, I just uploaded a screenshot.

Please have a look at my previous response, and the JSON Syntax link which should point you in the right direction.
