PUT to /activities/state responds with "Cannot merge!"

[Vjedi729]

PUT requests to /activities/state does not function properly. When sending a PUT request with a new activity ID, the response is:

{
    "code": 400,
    "message": "Original document is not JSON. Cannot merge!",
    "data": []
}

A GET request with the same parameters gives an empty body response with a status of 200.

My understanding is that PUT requests should not attempt to merge documents, so I am not sure of the source of this issue.

An example PUT request:

PUT /activities/state?activityId={{activityID}}&agent={{agentJSON}}&stateId=http%3A%2F%2Ftincanapi.co.uk%2Fstateapikeys%2Fregistrations HTTP/1.1
