Exception when loading MatterController

[Nik19792000]

Hi, I played around with node-red-matter, and I was even able to add one Device to Google Home, but shortly afterwards, Node Red failed to restart due to the following error:

1 Jan 12:03:45 - [info] [matter-server:MatterServer] Starting matter server

I re-installed node-red-matter and I can narrow it down to just adding a MatterControllerStatusNode and defining a MatterController and MatterServer. As soon as I do this, I get this error. Any idea, what's the problem?

I guess, I misinterpreted the purpose of the MatterController node. If I only want to create virtual Matter devices in NodeRed, then I shouldn't use MatterController node, right?
It's still a bit ideal to have the whole thing crash, if I pick a wrong node. I had to start NodeRed in safe mode to be able to delete the node.

Correct, The MatterController is used to pair with a matter device

[Apollon77]

Bu tin fact yes the code need to catch the error ideally :-)

Do you have a configuration to share to reproduce the crash?

[Nik19792000]

You can just add a Matter Controller Status node. Then add a new Matter Controller and use a valid pairing code (e.g. 749701123365521327694). When you deploy the flow, the error will show and node-red will stop.
