Fiori exception "no handler for data"

I have built a gateway service which successfully sends a pdf file. I used the media functionality and the GET_STREAM method to do this. It works in the Gateway cleint and when called from a browser.

However when I call the read method of the service from UI5, using the exact same syntax that works in the gateway (e.g. /sap/opu/odate/sap/ZINT_CRSTO_SRV/pdfSet(Ebeln='123')/$value ), I get an exception thrown in file datajs.js as "no handler for data" at line 7854.

The service is called successfully and returns a 200 status. The error is raised as the content type showing 'application/pdf' and there is no handler for this in the list

(there are handlers for 'application/json', 'application/atom+xml,application/atomsvc+xml,application/xml', 'application/xml' and 'text/plain')

I repeat, the gateway service works, the error is being thrown in UI5.

Any ideas where my error is?

from ui5 side, what you do after getting the data?

The data is not coming back, the exception is being raised inside the oModel .read call and therefore success callback function is not being called, I just get the oError object with a message that there is no handler for data and an uncaught exception in standard code.

I have attached a screenshot of the Chrome debugger as the exception is thrown.

Does this help anyone?

I am also raising an OSS message, but this forum is usually quicker ;-)
