HI @JT_Corrin 

 

Are you including the header "Content-Type." Usually, the value is JSON, so the key should be "application/json," but it depends on what you're doing.

 

Can you include it and let me know if it works?

 

If I have answered your question, please mark your post as Solved.
If you like my response, please give it a Thumbs Up.

Same thing just happened to me, got the same error.  For me, the fix was actually clicking into the Add new parameter box and setting the Mark As value to Read.   Hope this helps.
