Totally new to PA & almost clueless. However, my basic, simple flow doesn't work and I'm getting an error message which bottom line appears to be saying that the Post to Twitter element is a string, when an array is expected.
I've looked elsewhere to find a similarly simple flow to mine, but that WORKS! It appears to just like mine in it's compilation but I can't see why mine doesn't work.
All help gratefully received.
I've attached a couple of screenshots of the flow, I hope.
