Openhab Cloud Connector not working anymore after snapshot 1607

[zskadar]

Unfortunately, today’s 2.5.0~S1616-1 did not fix this issue :(.
Is there any way to report this topic to the developers, as an issue?

[wborn (Wouter Born)]

Maybe it’s caused by PR #5701 @J-N-K?

[J-N-K (Jan N. Klug)]

I‘ll have a look

[J-N-K (Jan N. Klug)]

Ok. I found the problem, still looking for a solution. It‘s two-fold. The servicemix-dependencies are not installed because the wrapped other dependencies don‘t declare them as required and the second problem is that the okhttp-servicemix imports javax.annotation.meta and the only bundle I found that is exporting that is the jsr305 servicemix but unfortunately that is also exporting javax.annotation which collides with the javax.annotation exported by the okhttp-servicemix.

[zskadar]

Thanks for your fast help, it seems it isn’t a tipical “it’s not a bug, it’s a feature” like problem, I hope you’ll find the solution soon.

[J-N-K (Jan N. Klug)]

Really strange. I just tried to reproduce the problem with an empty karaf container and there it works.

[frankie.delure (Frank Delure)]

So we better stay with #1607 @J-N-K ?

Can someone explain to me why this happens? @maggu2810 perhaps? I have no idea why the class is not found. Versions are ok AFAIK,

io.socket/engine.io-client/1.0.0 depends on com.squareup.okhttp3/okhttp/3.8.1 which is exactly the installed version.

Edit: With wrapped versions of the other two bundles it works. I’ll revert the change and re-add it when the osgiify-PR is merged.

[maggu2810]

Have a look at the package imports. Are you sure the package containing the class is imported?

They are imported. But maybe the problem is that the automatic wrapping done by karaf marks all imports as resolution:="optional" (which is not true for okhttp3). This bundle was installed before and already active when I installed the okhttp3-servicemix. I did not re-resolve the engine.io-client bundle, so maybe it did not pick up the available classes from that bundle…

My osgiified-bundles from my OSGiify-PR properly declare the dependency and therefore it’s working. Another reason to get rid of the karaf-wrapping ASAP.

[maggu2810]

If it is done the way you describe you need to refresh the bundle(s).

It is also possible to use the Karaf wrapping but declare that no import should be optional (that’s just instructions for the wrap logic of Bnd – yes that one is used in the background).

Hello,
Can you let us know when the new image is available for download.

i spend a lot of time getting openhab to work with the cloud connector just to find out it was broken 2 days ago.

i am running it on a synology docker image so i do not see an easy way to roll back to the image version 2 days ago(1607)

thanks

[wborn (Wouter Born)]

The wrapping changes have been reverted with PR #5743. There’s now a 2.5.0-SNAPSHOT build #1617 containing these changes. So hopefully the Cloud Connector is working again.

[GravityRZ]

thanks. online now

now i only need to make my devices visible.
tagging part still unclear

[Dries]

Thanks a lot! #1617 solves the problem!

[frankie.delure (Frank Delure)]

It appears to be fixed but after a while I get:

2019-06-20 15:01:28.802 [INFO ] [io.openhabcloud.internal.CloudClient] - Disconnected from the openHAB Cloud service (UUID = 7736390c-52ac-4e90-828e-xxxxxxxx, base URL = http://localhost:8080)

So I can unfortunately not confirm that this issue is closed.

[wborn (Wouter Born)]

There seems to be an issue with the Cloud now

See:

[SOLVED] MyOpenHAB-Cloud NOT Online - Alexa not working - OpenHAB-App no remote access!

Hello, since this morning my OpenHAB instance cannot connect to the openhabcloud. i have restartet the bundle, the instance, the server. i have reinstalled openhab from a fresh installation (with same uuid and secret) i get no errors in the log - its still ‘offline’ Sometimes, the session is online but remote access is not possible (Error 504 Gateway Time-out) Alexa tells "device is not reachable’ my internet connection is well. any public problems with the cloudservice at this time? c…

@wborn

Correct, doesn’t work with #1607 either.

[J-N-K (Jan N. Klug)]

I think this is a different problem.

[noppes123 (Ron)]

Running 2.5.0.M2 I tried to setup Myopenhab. Installed the add-on, registered successfully, and Myopenhab is online. However when trying to open my dashboard I get Error 504 Gateway time-out.
The openhab.log shows an error:

Is Myopenhab down or am I doing something wrong?
