Mattermost client not starting anymore

[tech348712013870132]

Mattermost (v5.13.2) doesn't start anymore after plugin activation.

Server log: At the beginning: {"level":"info","ts":1576092056.4354622,"caller":"go-plugin/stream.go:15","msg":"OnActivate kwmmmserverd","plugin_id":"kopanowebmeetings","source":"plugin_stdout"}

After a few moments:

"{"level":"info","ts":1576092583.047923,"caller":"go-plugin/stream.go:15","msg":"2019/12/11 19:29:43 kwm plugin error *errors.errorString while getting client configration: unexpected HTTP response: 404","plugin_id":"kopanowebmeetings","source":"plugin_stderr"}

Client (browser) side:

Is this a bug, or what are my misconceptions about this? :)

Now we are also seeing this kind of error:

@fbartels Do you have maybe any ideas regarding this issue?

[fbartels]

Hi @tech348712013870132,

I have seen your issue yesterday morning, but did not yet have time to look into it. If you need priority handling I suggest to get directly in contact with our support: https://kopano.com/support-info/

[tech348712013870132]

@fbartels Normal priority support should be sufficient for us at this point in time. We are just in the evaluation phase with your products and would like to get them up and running for further testing.

I hope we hear back from you :)

[fbartels]

I have now started looking into this.

Mattermost (v5.13.2)

is there a particular reason for using this version? Mattermost has by now also released 5.17.1

[tech348712013870132]

@fbartels The reason is that we have encountered a bug within the mattermost helm chart that makes it impossible for us to update it at the moment:

--> https://github.com/mattermost/mattermost-docker/issues/434

Is your plugin in general not compatible to this version of mattermost (v5.13.2)?

I would not expect so. the last time I tried it was with some 5.14 version.

I had this comment already open for several days, so before it gets lost I decided to finally send it. Maybe I find some time to actually test today.

[tech348712013870132]

@fbartels Thank you for your support! That would be very helpful for us.

And also a big thank you in general for your open-source efforts :)

[tech348712013870132]

Update: We are now on the newest version 5.18.0 of mattermost.

Now we have a new error (browser console):

TypeError: undefined is not an object (evaluating 't.teammate_id') — kopanowebmeetings_7d1a87f48235bc84_bundle.js:289

and

failed to get KWM config - retrying 3

@fbartels Any ideas about this?

[fbartels]

Hi @tech348712013870132,

I have done some tests on friday and wanted to first internally discuss things before updating here again. I think in the end the Error: Request failed with status code 500 error is a configuration mistake in regards to kwmserver (it's probably not reachable from mattermost), but the dealbreaker looks to be the Javascript issue.

In past versions one could reload mattermost and then continue to use the plugin, but that does not seem to be the case with the newer releases, where Mattermost stops loading when the kwmplugin is enabled.

This plugin was for us a bit of a test case to experiment with WebRTC and we have since then moved on and released Kopano Meet which is a full featured video conferencing solution (one to one, group calls, screensharing).

The original idea was to add some sort of integration from Meet back to Mattermost, but since Mattermost hasn't really caught on by our customers this is unlikely to happen anytime soon. Until then you can still install Meet stand-alone and just share group links manually into Mattermost.

I have added a notice to the readme: https://github.com/Kopano-dev/mattermost-plugin-kopanowebmeetings/commit/4802d55cb1c1184a65904d81b3d679befc66c2d3
