Hi Andrew,
I'm going to point you back to a few previous posts I made recently in other threads. I haven't looked yet at what might be the issue here, but try to solve those first as I see the same problems are seeping into this post/code again. Afterwards I'm willing to come back to this problem.
Start here, then move onwards to the link in there. Go back to that thread and try to understand why it failed there. If you can't figure that out, check the links and instructions from that post. If still not, ask for help there. I'm willing to explain it again, but the same error from that thread in June is now again slipping into your recent flows. Better to have that one solved once and for all, then figure out what is going wrong here and in other flows.
