So this happens at the first request? Are cookies enabled in your
browser? It could be that the browser handles cookies differently in
iframes? Can you see whether Orbeon Forms sends out a cookie and
whether that cookie is sent back by the browser?
Note that this particular error should no longer come up with Orbeon
Forms 3.6, as we have done quite a bit of work on state handling:

issue is with cookies.
