Robot Framework v 2.7.5 Soap UI Library throws error with a REST multi-part form POST request

[gwal...@navinet.net]

Using Robot's Import SoapUILibrary:

When I call a Soap UI Test Case with a Multi-Part REST post request I get the following MessagingException:

However I can successfully run this SoapUI Test case from Soap UI itself.

A json document has been attached to this multi part form request, called testDocument.json.
I have attached the stack trace log from the robot output.html log to this post.


This is the Rest Request Header:

Content-Type   multipart/form-data; boundary=----------------------------8d030e3574841ed

This is the Rest Request Content:

------------------------------8d030e3574841ed
Content-Disposition: form-data; name="metadata"
Content-Type: application/json
