Bug in FileMaker 16 Data API?

We're running into an issue with the FileMaker 16 Data API.


When using the REST API Find endpoint:

(Where: ICRS.fmp12 is our solution, wMoPicList is our layout)

And POSTing this body:

{"query":[{"MoPicID": "=100013715"}]}

The API returns:

{ "errorMessage": "Field cannot be modified",

"errorCode": "201"



If we turn off "Prohibit modification of value during data entry" on the MoPicID field, the API returns the correct data:


  "errorCode": "0",

  "result": "OK",

  "data": etc.



Has anyone else seen this behavior? Any workarounds short of enabling modification of a primary key?
