I'm trying to find a particular flow I copied from this site that worked, but recently I issued an npm command and all the flows vanished when I re-connected (OOPS)
Thanks for your response Zenofmud
Still didn't work, but I noticed one of the other flows was causing an erroe message when deployed ( even though disabled) so I exported the flows I had to a text file to save them, then deleted the flows apart from the new endpoint one, & tested that, and BINGO!
