Upload failure: saved_layer is None

[frafra]

Running SPCGeonode, GeoNode commit 287708d (Jan 15 2019).

File "./geonode/layers/views.py" in layer_upload
294. out[_k] = out[_k].decode(saved_layer.charset).encode("utf-8")
Exception Type: AttributeError at /layers/upload Exception Value: 'NoneType' object has no attribute 'charset'

I also see some errors on GeoServer:

18 Feb 13:08:19 DEBUG [geoserver.rest] - Failed to lookup template WorkspaceInfo
java.io.FileNotFoundException: Template WorkspaceInfo not found.

I see similar errors on GeoServer, like:

DEBUG [geoserver.rest] - Failed to lookup template g250_90.ftl,
java.io.FileNotFoundException: Template g250_90.ftl not found.

Before that I read:

WARN [common.sender] - Error while trying to initialize RabbitMQ Sender Connecton,
java.net.ConnectException: Connection refused (Connection refused)

RabbitMQ says:

[info] <0.589.0> connection <0.589.0> (10.0.0.16:41466 -> 10.0.0.186:5672): user 'guest' authenticated and granted access to vhost '/',

...and...

I see the standard Geonode black bar on top, like I has been kicked out, with no possibility to login directly (CSRF error), so I have to refresh the page. https://screenshots.firefox.com/3GFdEpB6m6yAtxaF/nindocker02.nina.no

ASYNC_SIGNALS=False does not mitigate the issue.

It looks like the Rabbit MQ error is not critical and can be ignored (it happens even in successful tests) and even the "file not found" message seems not relevant. A bit hard to debug with all these non-relevant errors :-) It is not a network issue either.

It seems to be linked with the data volumes, because using the same configuration with a different set of volumes fixes it; maybe some incompatibilities between 2.8 and current master.

I can confirm this error happens also on fresh and working docker setups. I just tried to upload an archive:

Workaround: I created a fresh instance and moved the data with the aid of some tools I developed.

It seems hard to me to understand what could be the issue because GeoNode is not able to display its error properly. See: #4321

[gannebamm]

I get those errors, too. I used SPC with ASYNC_SIGNALS=False and can confirm it does not change the outcome: I am unable to upload files and will be logged out by doing so.

[afabiani]

@gannebamm any chance to test again with these changes?

#4353

[gannebamm]

@afabiani My error was related to SSL misconfiguration. The message:

File "./geonode/layers/views.py" in layer_upload
294. out[_k] = out[_k].decode(saved_layer.charset).encode("utf-8")
Exception Type: AttributeError at /layers/upload Exception Value: 'NoneType' object has no attribute 'charset'

was just a culminating message, which was not related to the original failure.

[afabiani]

@gannebamm yeps, that PR aims to avoid hiding those errors and trying to push up the original cause to the interface (as much as possible)
