@ThomasG77 thanks!! I used your code to write a version for a buffer result = processing.run("native:buffer", {'INPUT':QgsProcessingFeatureSourceDefinition(layer.id(), True), 'DISTANCE':2.5, 'SEGMENTS':5, 'END_CAP_STYLE':1, 'JOIN_STYLE':1, 'MITER_LIMIT':2, 'DISSOLVE':True, 'OUTPUT':'memory:'}) QgsProject.instance().addMapLayer(result['OUTPUT'])

Did you change the path '/data/convexhull.shp' to adapt to your own system? I've made some changes to use "in memory" layer to avoid the issue and another last line to add layer to the current QGIS project

It says _core.QgsProcessingException: There were errors executing the algorithm. Probably there's some error in the layer. Thanks anyway for helping me!

| Feb 22, 2020 at 16:16 | comment | added | Lorenzo | Sorry, in my case this code produces nothing. I have no idea what the problem is. | |
| Feb 22, 2020 at 16:08 | comment | added | ThomasG77 | Made change to merge all selected geometries. Should do what you expect due to your changes in edited answer | |

It works and only produce one convex hull polygon (normal with feat = layer.selectedFeatures()[0] part)

| Feb 22, 2020 at 15:53 | comment | added | Lorenzo | What happens if you select multiple polygons? | |

| Feb 22, 2020 at 15:40 | comment | added | ThomasG77 | I also use a polygon layer... Did you really select a feature in the original layer? | |
| Feb 22, 2020 at 15:39 | comment | added | Lorenzo | Hi thanks for your answer. But also this solution does not work. Maybe the reason is that I'm using a polygon layer? | |
