Plugin version: 1.3.1
QGIS version: 3.16.2-Hannover Hannover, f1660f9da5
Operating System: Windows 10

Description

Relational mode (GMLAS) scenario - Local test scenario > steps 1, 2 then directly 5
'Load layer list’

RuntimeError: HTTP error code : 404

To Reproduce

Follow https://brgm.github.io/gml_application_schema_toolbox/testing/scenario_mode_gmlas_local.html Do step 1, 2 and directly 5 as described.

For step 5 on groundwaterlevel_href > (‘Load’ button click) > ‘Options for xlink:href loading’

“Load layer list’ : click

RuntimeError: HTTP error code : 404

Another way to test this is directly loading in GMLAS mode the URL of this file; no need to load the BoreholeView.xml file to have this bug.

Expected behavior

the Layer list shall be enriched by the list of the features retrieved in the XML

Additional context

the XML file (raw.githubusercontent.com/BRGM/gml_application_schema_toolbox/master/tests/basic_test_scenario/3_GroundWater_Quantity_Monitoring_Facility.xml) only raises a Warning in XMLSpy (on INSPIRE xsds)
and the XML file is properly retrieved in XML Mode so no 404 on the file itself (nor the XSDs otherwise XMLSpy would have raised issues)
was also a bug on V 1.3.0
