Docker watcher throws TypeError

[rasmuslp]

Greetings,

I'm getting this in my Docker logs of WUD:

TypeError: Cannot read property 'newVersion' of undefined
    at Result.equals (/home/node/app/model/Result.js:15:42)
    at isSameResult (/home/node/app/watchers/providers/docker/Docker.js:42:30)
    at EventEmitter.processImageResult (/home/node/app/watchers/providers/docker/Docker.js:67:20)
    at EventEmitter.emit (events.js:314:20)
    at Object.emitImageResult (/home/node/app/event/index.js:11:18)

    at processTicksAndRejections (internal/process/task_queues.js:93:5)
    at async Promise.all (index 1)

It shows up once for each time WUD checks the default local Docker watcher:

{"cron":"* * * * *","socket":"/var/run/docker.sock","port":2375,"watchbydefault":true}

Let me know if there is any information I can provide to help debug this.

Hi,

Based on the second issue you've opened, I guess that some containers are detected and some others aren't?
Can you run wud with the env var WUD_LOG_LEVEL=debug and paste the log here?

Thanks

[rasmuslp]

Actually all showed up, except for the issue described in #17.
However, after I removed the home-assistant container I had running, the error seems to have disappeared.

I'll try to see if I can recreate the issue with debug logs enabled.

This container was the only one that did not have a wud.tag.include label. But it's my impression that these are optional?

I've pasted the current debug logs below. While they don't seem to show the error, they do highlight another peculiarity: What's up with the arch in the logs?

I'm running this on a Raspberry Pi 4, so I would expect something arm, if specified. However, for portainer/portainer-ce:2.0.0, where linux/arm is available, it shows up as amd64.

[fmartinou]

Yes, all labels are optional (incl wud.tag.include).

Regarding the weird arch on portainer, wud gets the values from the docker socket like a simple docker image inspect would do.

If you run docker image inspect --format='{{.Architecture}}' portainer/portainer-ce:2.0.0, what does that return?
arch or amd64?

[rasmuslp]

Aha, that returns amd64.

Hi,

With version 3.1.1, the error Cannot read property 'newVersion' of undefined should be gone.
