Hello All,

I am trying to implement a workflow that starts off with an EmailReceiver (like what Howard has posted about) to kick off the workflow. So, I use the Email Receiver QPAC as step 1 and I start the workflow by invoking it through the web services (http://hostname:8080/services).

I'm suddenly getting this error and cannot tell from the message where the exact issue is:
