Raspberry Pi 3B, running Bullseye (just performed full update)
Just updated as above and now node-red-contrib-telegrambot is no longer working (See GIT issue 343. I have tried to back the that node to 15.1.6 and also reinstall that node etc but no effect.
Next I want revert NODE from version 20.8.1 back to version 18.x.x but unsure how to do that as Node-red and nodes seem to be 'configured' to Node.
Can I just run the raspi install script with the tag --node18 (Noting when I upgraded --node20 failed! so I manually updated)
Yes - that should do it. You will also need to go into your ~/.node-red user dir and run
npm rebuild afterwards so ensure any binaries are rebuilt against node18.
Thanks @dceejay i wondered how that would be sorted.
You should also raise an issue against that node because Node.js v20 moves to LTS this month if it hasn't already.
Doesn't the script do that automatically if it installs nodejs?
It did, within 24 hours of raising an issue on the Telegrambot node.
I can confirm that changing Node back to node18 fixed the problem which appears to be a node20 compatibility problem in node-red-contrib-telegrambot
