OIC - SOAP request payload with base 64 binary content

Summary

OIC - SOAP request payload with base 64 binary content

Content

I have a OIC's SOAP integration which payload contains a base 64 string that represents a jpeg.

The string I am using on tests has about 400kb.

I already checked the base 64 binary string is valid. I am able to convert it back to an jpeg image using another tool.

If I make a SOAP request without the string, the integration starts and runs ok. If I provide it, the integration does not even start (no instance is created) and I receive a NoHttpResponseException on SOAPui.

I've already tried setting element type in WSDL's schema as string and base64Binary.
