Node-red-mcu-plugin error when reinstalling

[Frida]

After reinstalling node-red and @ralphwetzel/node-red-mcu-plugin, I've encountered these issues:
1: After first start of node-red this error came, see pic01
2: I removed the =, and tried again.
3: After second start of node-red this error came, see pic02
4: I removed the =, and tried again.
5: After the third start everything was normal.
But it didn't install @moddable-node-red, shouldn't it anymore?

When I tried a previous flow which worked before fresh install, this error comes, see pic03.

How do I proceed?

I don't think ??= works with nodejs 14. Upgrade to 18 and it should be ok.
14 is out of support in a months time anyway.

You're facing this issue - as @Colin stated - due to the node.js version you're using.
??= is only supported by node.js >= v15.0.0 ... a fact that I tend to ignore continuously. Sorry for that.

By removing the = you yet change the code significantly ... thus it breaks with the error you see in pic#03.

I'll provide a fix for that later today ... so it should work again with your environment.
Sorry for the inconvenience...

I've published a v1.3.1 of the plugin - which should be visible in the Node-RED "Manage Pallette" sidebar option in a few minutes.
In this version, the two issues you found are reverted to a syntax that Node.js v14 understands.

In the meantime I have updated to node 18 now. My simple program with a switch and an LED seems a bit sluggish.
When I press it, sometimes it responds immediately, and other times after some time.

If you want, you may post the flow data here & we'll check if we can support...
