[Qgis-user] Error while processing "servicearea"

[Jean-Baptiste Desbas]

Hello,

I want to use the serviceareafromlayer alg in a python script, but it give
me an error :

Traceback (most recent call last):
File
"C:/PROGRA~1/QGIS3~1.0/apps/qgis/./python/plugins\processing\algs\qgis\ServiceAreaFromLayer.py",
line 264, in processAlgorithm
fields, QgsWkbTypes.MultiLineString, network.sourceCrs())
Exception: unknown

I can successfuly lunch that alg with the same input layer from the GUI, so
what's wrong with my code ?

Here is the code : http://paste.debian.net/1023040/

Thanks,
