I am trying to delete and create pass type ids. In both cases I get error 400 which means that at least my token is valid.
In case of deletion I make a DELETE request to /v1/passtypeIds/{id} where {id} is 10 character string. And I get 400 error back with basically no (or rather nonsensical) explanation: "JSON processing failed". What JSON? There is no request body for this request.
