Unexpected Type Error when calling makeImageRequest

I'm getting the below error in ERA. At line "View.makeRequest:283" is "Comm.makeImageRequest(url, parameters, options, method(:responseCallback));". Since I don't have the source code for Rez, does anyone know what might cause the "Unexpected Type Error"?
