AttributeError: 'NoneType' object has no attribute 'split'

[Tjeu]

When I try to connect to the following service with WFS I get the error below:

I just want to give feedback that I am also seeing this error.
Windows 10, OSGeo4W-64 installation, QGIS 3.8.0 Sansibar, toolbox version 1.2.0
and btw. no proxies defined in QGIS ;-)

Just to give some more feedback:
This actually happens while using the load wizard. I select the "load in relational mode" and in the following dialog I click "load layer list" and there the error occurs.

Further addendum from my QGIS console:

settings = QSettings()
f = settings.value("proxy/proxyExcludedUrls", "")
print(f)
None

I believe the test should include if excludes is not None somewhere there in addition.

I'm having having the issue with loading the WFS-service: https://haleconnect.com/ows/services/org.292.c3955762-73a3-4c16-a15c-f3869487a1e3_wfs?VERSION=2.0.0 with the wizard. On the moment I connect. There is an error.

I'm having the same issue.

I have been able find out that using clean newly-created unmodified user profile for QGIS allows to use plugin without error.

To create new default user profile from scratch: delete/rename "default" user profile in
/Users/macos_username/Library/Application Support/QGIS/QGIS3/profiles. This causes QGIS to start as "newly installed" – you will get all the welcome messages etc.

To replicate previously described issue: make adjustments to QGIS preferences (which are saved in user profiles). I have tested following various changes in preferences and I'd like to generalize that any change to user profile causes the error (however this might not entirely true).

At least following changes cause the error:

• Changing localization of QGIS
• Changing default CRS setting for newly created project
• Changing default CRS setting for newly created layer
• Changing default path for print templates

Reverting changed QGIS preferences manually back to default options does not fix the error. Additionally using QGIS inbuilt "revert preferences to default" command does not fix the error either. It appears that only manually deleting/renaming default user profile in file system fixes the error.

Hope that this helps to solve the issue!
