Error Details - Xmlmc method invocation failed for BPM

Hi, 

I'm hoping someone will be able to help with an error I kept getting when trying to build a Workflow out. 

 

I'm getting the attached error when my workflow gets to the 3rd stage in the process and I can't seem to work out what it means?

I don't seem to have any errors in the actual workflow config so I'm at a loss!

It looks to me like you're assigning a task to a variable, and that variable contains the request ID rather than the ID of the user/group you wish to assign to.
