Hello all,
I am strugglying since a few days with the remote execution using Docker containers.
Finally, I found a docker containers composition that fits realitvely good with my needs:
compose.yaml:
version: "2.2"
services:
selenium_hub:
image: selenium/hub:3.14.0-curium
ports:
- 4444:4444
samsung_galaxy_web_5.1.1:
image: budtmo/docker-android:emulator_11.0
privileged: true
# Increase scale number if needed
scale: 1
depends_on:
- selenium_hub
#- real_device
ports:
- 6080
volumes:
- ./video-samsung_5.1.1:/tmp/video
environment:
- DEVICE=Samsung Galaxy S6
- CONNECT_TO_GRID=true
- APPIUM=true
- SELENIUM_HOST=selenium_hub
- MOBILE_WEB_TEST=true
- AUTO_RECORD=true
Usage: docker-compose -f compose.yaml up
The containers start, that’s fine.
My issue comes when my test wants to start the application, but first, here is the remote configuration:
And here comes the error:
and in plain text, the error (prunned for display reason):

Has anybody an idea how to remove the platform value from the desired capabilities?
I didn’t provide it but Katalon adds it by itself 
Thanks in advance!!
