Error Message When Invoking in OIC Integration

I have pushed like 6 contacts(Segment) from eloqua into OIC but i got an error at "INVOKE CONTACTS FROM ELOQUA" ADAPTOR. Here is the error message:

"Import_contacts {http://schemas.oracle.com/bpel/extension}runtimeFault : Error sending bytes: <a target="_blank" style="cursor:pointer !important" title="Link to Customer Connect Forum for this error code. It will open in a new browser tab." href="https://cloudcustomerconnect.oracle.com/resources/704fc67d61/search?find= ORABPEL-15236

"> ORABPEL-15236

</a>

."

Anybody familiar with this?
