aravis python assertion errors

[nagyilles]

I am importing the package as follows:

from gi.repository import Aravis
self.cam = Aravis.Camera.new(name)

The camera opened successfully (Baser acA1920-155um USB3) :

I am able to grab images, but I am getting the following error messages:

** (python:9975): CRITICAL **: 12:23:50.795: arv_buffer_get_part_pixel_format: assertion 'arv_buffer_part_is_image (buffer, part_id)' failed

I have tried on 2 different machine with Ubuntu 20.04.1 LTS and different cameras.

Could you attach a short sample software that shows your issue ?
