Thank you for the reply, and I totally agree. We've been running jserport on many Windows servers for several years without issue. Recently, we've begun moving a few development machines over to Linxux and we know just enough to be dangerous.

It does appear to be more of an issue with either node.js or PM2. I was just hoping someone here might have seen a similar error when following the install steps.

I will continue researching the issue looking more closely at PM2.

Thanks.

I have an Ubuntu 20.x server where I'm attempting to run jsreport as configured per the instructions here:
https://jsreport.net/learn/ubuntu

I can start the server manually just fine and it works fine using
pm2 start server.js

However, when attempting to use the startup after a reboot, the server starts quickly then immediately throws the following exception in the pm2.log:

I have another server with the same configuration and it works perfectly, and I can't find any differences between the two.
I've completely uninstalled and re-installed with the exact same results.

Any help or suggestions are appreciated.
