Okay thanks. Just to be sure : is that normal that I get QgsVectorLayer with for example qgis:intersection and with the same principle I get a string in the output of qgis:difference ?

| Apr 24, 2019 at 16:53 | comment | added | dmjf08 | It works but the output of the algorithm is not a QgsVectorLayer as usual, it's a string "output_...". How can I get the QgsVectorLayer ? | |

yes, but you have to add it to the project QgsProject.instance().addMapLayer(layer['OUTPUT'], False) try that

I try to use it with a temporary layer like following : 'OVERLAY': QgsProcessingFeatureSourceDefinition(layer['OUTPUT'].id(), True), but it returns Could not load source layer for OVERLAY : output_.... not found. Can't the layer be temporary ?
