Description

Hello,

if you try to load a layer within a processing script using : layer = iface.addVectorLayer("path2asimpleshapefile.shp","test", "ogr").

The layer will not be added on the canvas. But the layer object will be OK.

NB: I noticed that it is working if you remove all parameter from the script But it will not work if you add any parameter ( QgsProcessingParameterVectorLayer for example)

It was working fine in 2.18.

thank you,

This isnt thread safe, so not possible in 3.x. use context.addLayerToLoadOnCompletion instead
