I recently moved a bunch of CPE over to GenieACS (latest pulled from github), their inform interval is set for 3600 seconds but I have not recieved another inform since 12:31:44pm yesterday. I checked the services and they are all running but found this error was spit out by genieacs-cwmp.

Your title and the body of your message are not consistent. Did you pull the v1.2.0 tag, or did you pull latest? There have been several fixes since v1.2.0.

If you are running v1.2.0, I suggest you update to master.

Ah yes, I should’ve checked github first. I apologize. It looks like I am running a copy from Sept 9th from github and I see recent fixes.

I have updated from the latest master on github and let it run for a bit. Came back from lunch and saw this error again.

Are you sure you’re running the most up to date version? As of 1.2.1 unhandled promise rejections should never occur. You should get a regular exception instead.

</div>

I double checked everything and can confirm that I am running 1.2.1.

When I run it manually instead of starting from systemd

```
root@acs:/home/genieacs/genieacs# /home/genieacs/genieacs/dist/bin/genieacs-cwmp
2020-09-17T04:32:28.746Z [INFO] genieacs-cwmp starting; pid=2074 version="1.2.1+20200916172228"

```

I also modified the systemd file on my previous install to point to this location.

```
[Service]
User=genieacs
EnvironmentFile=/home/genieacs/genieacs/genieacs.env
ExecStart=/home/genieacs/genieacs/dist/bin/genieacs-cwmp

The same with genie-ui. A lot of “UnhandledPromiseRejectionWarning: Unhandled promise rejection.”  
version=“1.2.1+20200909044125” from npm

</div>

So I was wrong when I assumed the linter rule that I added recently to guard against unhandled promise rejections covers every possible case. @tripout, just fixed this edge case so please update from git master and try again.

@npoxBocT, you’ll just need to upgrade your Node.js to 12 or 14.

That’s identical to what I got. Can you confirm no changes have been made to the code?

There should not be such file. Looks like you have another copy of the project under `ui` directory…
