Uncaught Exception question

[alnospam64]

Hi,
I am running Openhab 3.2 on a Raspberry 4
I have managed to get everything installed (standard instal) and if I run the js file from the opt/ring-mqtt folder all is fine

but if I let the service run I get this error

Any idea of what is going on?

The second pre-requisite in the standard install document notes that rtsp-simple-server must be available in the system path. The "ENOENT" error means "File not found" so it means this requirement has not been met. Where did you install rtsp-simple-server and do you have that location in the path for the services file?

You might want to consider a Docker install which takes care of all of this for you.

Hi, thanks for the quick reply

I have installed the rtsp-simple-server in /usr/local/bin/rtsp-simple-server
and added
export PATH=$PATH:/usr/local/bin/rtsp-simple-server
in my .bashrc and .bash_profile

I will try the docker method but I am confused on why it would work if I did run the js file manually

[tsightler]

Assuming you are using the example ring-mqtt.service file included in this repo then it's because that file does not include /usr/local/bin in the path so you'll need to modify the file to include it. Services don't generally run under user context so adding to .bashrc/.bash_profile are not really useful for that case. You can look on line 11 to see where you need to modify the path.

Thanks. Now I have a13 error EACCES.
I am going to try the docker route... Thanks

Clearly a permissions related issues, but I'm not sure how that's possible since the example ring-mqtt.service file is setup to use root. If you've changed it to another user then you'll need to make sure permissions are correct on the /opt/ring-mqtt directory and for the rtsp-simple-server (maybe you didn't set execute bit?).

Good luck!
