What was the expected behaviour?

The test is expected to run in cloud environment specified, as like in local.

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Are you running with the detox patch Browserstack has provided? They add the cloud config, without that patch it doesn't exists so you cannot run your test. So you have to build with the regular detox package and then run with their detox package.

For me Detox with browserstack works when I run it locally, but when I try to run the exact same script from the pipeline, my app starts, shows my homeScreen for half a second and then crashses (shows a white screen, for the rest of the test).
