Derive Mapping

[rsoeldner]

Hi,

any way to derive the mapping? I just received some errors for derived Aeson instances...

Response {responseStatus = Status {statusCode = 400, statusMessage = "Bad Request"}, responseVersion = HTTP/1.1, responseHeaders = [("content-type","application/json; charset=UTF-8"),("content-encoding","gzip"),("content-length","204")], responseBody = "{\"error\":{\"root_cause\":[{\"type\":\"illegal_argument_exception\",\"reason\":\"mapper [experimentStepSet.stepMethod.methodCategory.categoryParameter.parameterValue.contents] of different type, current_type [text], merged_type [long]\"}],\"type\":\"illegal_argument_exception\",\"reason\":\"mapper [experimentStepSet.stepMethod.methodCategory.categoryParameter.parameterValue.contents] of different type, current_type [text], merged_type [long]\"},\"status\":400}", responseCookieJar = CJ {expose = []}, responseClose' = ResponseClose}
