POST JSON data denormalization error

I created rest resource plugin in a custom module and need to send some JSON data with the request, and access it in the post function. At the moment my post function does not do anything but return some dummy JSON data so I know it is working.

It seems that whenever I try to pass JSON data with the request, it will give me this error: “Could not denormalize object of type , no supporting normalizer found.”

If I then try to get this data using file_get_contents(‘php://input’), it will give me a 403 forbidden error. But if I try to return the same data that I get from file_get_contents(‘php://input’) from the post function, I get the normalizer error again.

I wasn’t able to find much information on even making this REST resource and even less on this issue now, so if anyone has any input I would greatly appreciate it, thanks!
