I'm having some terrible issues with FLOW pasting in Node-Red. I'm over in Spain right now for the summer where my Node-Red setup is months old. I could not safely remotely update Node-Red, NPM etc here to the latest versions from the UK without chancing the entire Spanish installation. The UK uses a later Node-Red and NPM (10 instead of 8) and updated nodes (both the UK and Spanish versions work just fine normally)..
So I brought over a PI 3 (same as I have here) with my UK setup, renumbering the fixed IP address to a test address here. If I start up the Pi, all is well (but of course set up for UK devices and so not controlling real things yet. But if I delete all my flows and reboot, then start copying my Spanish flows across from the Spanish working setup, I get horrendous flow replication and eventually have to revert to a backup.
For example - the first flow is called INIT and simply does some initilisation of variables. In the newly emptied NR board, I import the nodes from the old Spanish INIT flow....via the clipboard, then rename the new FLOW1 to INIT. That seems to work. I then make a new FLOW1, import the second flow contents. Not only does that paste initially seem to work bar one missing node, but the next thing I know there are dozens of flows called INIT and the whole thing starts to fall apart with nodes sitting on top of other nodes.... has anyone else come across a similar situation? Thank heavens doe rpi-clone.. I revert to a backup made before I started to make changes and all is well, but upgrading the setup here is not looking promising right now.
