Re: [Qgis-user] Issues by using a script inside the python console
Hi Richard,
thanks for your hint! By adding the QgsProcessingFeatureSourceDefinition, it
works :)

I use succesfully the following in a script and a plugin:
# Voronoing ONLY the selected
# NOTE: the colon (:) behind 'memory' in the 'OUTPUT' param is
mandatory,
# else QGIS will create a geopackage!
selected = True
params = {
'INPUT': QgsProcessingFeatureSourceDefinition(point_layer.id(),
selectedFeaturesOnly=selected),
'OUTPUT': 'memory:',
'BUFFER': 5,
}
result = processing.run("qgis:voronoipolygons", params)
Maybe you can use that to reconstruct your call?

[Qgis-user] Issues by using a script inside the python console
Hi all,
I am currently using the "Snap to Roads" script inside my qgis environment, to
match gpx-points to the OSM
(https://spatialthoughts.com/2020/02/22/snap-to-roads-qgis-and-osrm/).
I am able to execute the Script by using the QGIS Script Environment:
[cid:317d9d57-3f6d-41dd-8234-b68dcfa66fc2]
Unfortunatly, I would like to run the script via python console inside QGiS,
but this doesn't work at all ...
By executing the following command:
layer_SnappedLine = processing.run("script:snap_to_roads",
{'INPUT':layer_GPX_Points['OUTPUT'],
'SERVICE':'http://127.0.0.1:5000',
'TOLERANCE':10,
'OUTPUT':'TEMPORARY_OUTPUT'})
I receive the error message:
"Traceback (most recent call last):
File "C:\PROGRA~1\QGIS32~1.10\apps\Python39\lib\code.py", line 90, in runcode

line 205, in runAlgorithm
layer = context.takeResultLayer(result) # transfer layer ownership out of
context
TypeError: QgsProcessingContext.takeResultLayer(): argument 1 has unexpected

Can anybody help me with this issue? I am using QGIS Version 3.22.10
Regards and thanks,
Marie
