Can't list or add a datastore for Geoserver

[rfazimut]

Describe the bug
With the current version, from the connection tab, I cannot add a database or iterate the list of database defined on the geoserver with this message:

File "C:\Users/rfortin/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\geocatbridge\servers\views\geoserver.py", line 184, in _addGeoserverPgDatastores
datastores = list(chain.from_iterable(worker_result))
TypeError: 'KeyError' object is not iterable

To Reproduce
Steps to reproduce the behavior:

1. Add connection Geoserver
2. Specify parameter and credential
3. Select File-based...
4. Test Connection == OK
5. Change storage to Import into PostGIS database (managed by GeoServer)
   Datastore are defined on the server
6. CLick Add datastore
7. Specifiy parameter
8. Click OK
9. The error message shows.

Expected behavior
Datastore is added or listed from the Geoserver

Thanks for reporting @rfazimut.

Three additional questions I have:

1. If there already is a PostGIS datastore on GeoServer (defined manually perhaps using the GS web UI -
   not using Bridge), and you select Import into PostGIS database (managed by GeoServer) (so at step 5 above), can you at least confirm that the combobox below it gets populated with some existing datastores?

2. Which parameters (at step 7) do you specify? I don't mean the exact values (user, pass, etc.) but I would like to know which fields you are setting.

3. After step 8 (OK), does the "Add datastore" dialog close first before the error appears?

Thanks,
Sander

Hi! Answer to your questions : 1. Yes. There are defined datastore on the Geoserver. The error come as soon as we select select Import into PostGIS database (managed by GeoServer) 1. Here an example ***@***.*** 1. Yes. It tries to refresh the list of datastore and we get the same error. I tried also using the other option (direct connect) after a connection to the same PostGIS database as been defined. In this case, we get a different message when we try to publish. Errors: Traceback (most recent call last): File "C:\Users/rfortin/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\geocatbridge\publish\tasks.py", line 129, in run _publish(layer, publish_fields) File "C:\Users/rfortin/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\geocatbridge\publish\tasks.py", line 65, in _publish self.geodata_server.publishLayer(lyr, pub_fields) File "C:\Users/rfortin/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\geocatbridge\servers\models\geoserver.py", line 277, in publishLayer self._publishVectorLayerFromPostgis(layer, db, fields) File "C:\Users/rfortin/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\geocatbridge\servers\models\geoserver.py", line 669, in _publishVectorLayerFromPostgis self.request(ds_url, data=ds, method="post") File "C:\Users/rfortin/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\geocatbridge\servers\bases.py", line 279, in request result.raise_for_status() File "C:\PROGRA~1\QGIS32~1.5\apps\Python39\lib\site-packages\requests\models.py", line 941, in raise_for_status raise HTTPError(http_error_msg, response=self) requests.exceptions.HTTPError: 500 Server Error: Server Error for url: http://192.168.10.207:8080/geoserver/rest/workspaces/evalzonage49048/datastores At this point, we have been unable to publish layer to Geoserver other then using the geopackage option. It is not clear to me if checking the option “Reference existing PostGIS tables (if exists)” will actually just publish the layer and not copy the data which is already there. Is that what it is supposed to do? Robert

Thanks for the info @rfazimut.

Besides the fact that this is not supposed to happen and we need to fix the user experience (in case there is an error accessing/listing the datastore), there also seems to be something peculiar about your datastore(s).

Since you get a 500 when using the Direct Connect approach, could you perhaps share the error that GeoServer throws (see GeoServer logs in web UI)?

Concerning the Reference existing PostGIS tables (if possible) option, you can right-click on it to get more info as to what that does:

That option will only work if:

• The QGIS input layer source is a PostGIS vector/feature table;
• You are using the Import into PostGIS (direct connect) storage method.

In that case it will work the way you thought it would.
