The POST endpoint expects objects to be in an array, however, users may submit a single object that isn't nested in an array. The endpoint should check for this an wrap it in an array if necessary.

-->
response={"statusCode":400,"payload":{"message":"The request body must be in the form [{\"header1\": \"value1\", \"header2\": \"value2\"}, ...]"}}
