Hi developers,
Recently some users of my plugin started getting errors in the code that
creates a .gpkg file with a table. I wrote a piece of test code:
gpkg_fn = '/home/raymond/tmp/test.gpkg'
md = QgsProviderRegistry.instance().providerMetadata('ogr')
conn = md.createConnection(gpkg_fn, {})
fields = QgsFields()
fields.append(QgsField('key', QVariant.String))
fields.append(QgsField('value', QVariant.String))
conn.createVectorTable('', 'test', fields, QgsWkbTypes.NoGeometry,
QgsCoordinateReferenceSystem(), True, {})
That last line *sometimes* results in this error:
_core.QgsProviderConnectionException: Could not retrieve driver for
connection
I cannot reproduce the error on my laptop (Linux), but Richard tried a
few QGIS versions in both Windows and Linux and *sometimes* got the
error and sometimes not. Even in the same application, the error
disappeared after running another version of QGIS simultaneously... :/
No clue if this error is GDAL or Qt or whatever related, pretty puzzling
for me. Hope anyone can help!
Kind regards,
Raymond
