No NMEA2000 data anymore

I've upgraded to the latest signalk server and suddenly i am not receiving and NMEA2000 data anymore. It fails with the message: Cannot read properties of undefined (reading 'createRawChannelWithOptions'). This could be coincidence, i've also installed mqtt-gw plugin (now disabled). I am using a Sailhat (SH-RPI) to receive the data. It was receiving fine two weeks ago, i haven't made any changes to the NMEA2000 connection settings. I'm running node v22.15.0 (saw the other posts about 2.14.0). Downgrade to 2.13.5 failed with

see https://discord.com/channels/1170433917761892493/1385877537145618478 I got the same error after upgrading.

Remove that directory in the error message The .signalk-server.1toV….. You might want to try 2.14 again. That issue you’re having happens when something terrible goes wrong during install

BramOP•3mo ago

Thx. Removed the folder. You mean reinstall 2.14 or just reboot?

Scott Bender•3mo ago

Reinstall 2.14

BramOP•3mo ago

Ok, will lay course close to land to stay in 4G range 😉

Hannes•3mo ago

i needed to uninstall and install again. anything else did not work dont forget the backup 😉

BramOP•3mo ago

How do i uninstall? good reminder just remove node_modules?

Hannes•3mo ago

npm uninstall signalk-server

once again run npm install signalk-server maybe with sudo, depending on your system.

Scott Bender•3mo ago

Yes. Need sudo. and it’s “sudo npm install -g signalk-server”

BramOP•3mo ago

Thanks a lot working on it... Will this kill the installation process? I guess my 4G is flaky at the moment

Would there be a way for npm to first download signalk to the pi and than install from that? I guess that will be difficult with dependencies though

Scott Bender•3mo ago

Yeah, not that I know of

BramOP•3mo ago

Pfff again disconnected... will try in the harbour. Thx so far Will try using vnc, because i think it is the connection with the pi that might be the problem. In vnc the npm process would keep running.

Scott Bender•3mo ago

you coud also run it in the background

BramOP•3mo ago

True with & at the end wasn't it?

Scott Bender•3mo ago

need to redirect the output, so sudo npm install -g signalk-server > /tmp/npm.out & 2>&1

BramOP•3mo ago

thx will try that the next time. VNC failed for some reason. Tried running it in the bckground. After the connection was reset again i couldn't find /tmp/npm.out (i could before it disconnected). Though with top i see an active node process running, so i guess its doing something. Strange

Scott Bender•3mo ago

Might be something to do with sudo. Not sure I ever tried that before…

BramOP•3mo ago

Had to reinstall two more times but now it works. Thx again!
