Error fetching report using runReport SOAP service

Summary:

Hi,

I am fetching a report in OIC from Oracle otbi using the runReport SOAP webservice. I added the service that's being executed.

In OIC i'm then mapping the reportBytes of the response to write a file using this opaque schema:

After that i'm reading the file again using this xsd schema:

But at the read file step, i'm getting this error.
"SAX Exception in translator.

SAX Exception raised while trying to  SAX Parse InputStream  .

Please make sure that the xml data is valid."

Is there anything wrong with my sample files?
These are also the fields that are being fetched from the report:
