Can't export lines to geopackage due to duplicated column names

[asongtoruin]

What is the bug?

Hello, I have successfully (and very easily!) downloaded some OSM data - however, when I try to save the lines output to a geopackage, QGIS gives an error due to duplicated column names. I can't seem to find the error as copyable text, so here's a screenshot:

From looking at the data, it seems as though the download includes both type and TYPE as separate columns and I believe geopackage insists on all lower-case column names.

It looks like this might be a quirk on the OSM-side, but would there be any way for QuickOSM to pre-process the data and ensure uniqueness of (lower case) column names?

The query I ran is as follows:

{"query": ["[out:xml] [timeout:25];\n(\n    node( {{bbox}});\n    way( {{bbox}});\n    relation( {{bbox}});\n);\n(._;>;);\nout body;"], "description": ["All OSM objects in the canvas or layer extent are going to be downloaded."], "advanced": false, "file_name": "", "query_layer_name": [""], "query_name": ["Query1"], "type_multi_request": [[]], "keys": [[""]], "values": [[""]], "area": [""], "bbox": [{"__extent__": "-3.246191445775106 55.94311319126636 -3.155759203527417 55.97216842876525"}], "output_geom_type": [[{"__enum__": "LayerType.Points"}, {"__enum__": "LayerType.Lines"}, {"__enum__": "LayerType.Multilinestrings"}, {"__enum__": "LayerType.Multipolygons"}]], "white_list_column": [{"multilinestrings": null, "points": null, "lines": null, "multipolygons": null}], "output_directory": [""], "output_format": [""]}
