Detox + Expo dev client - launch arguments are always empty

[PeKne]

If I build a production version of the detox test app, I can correctly access the launch arguments passed by the test runner. But if the test app is an Expo development client, the launch arguments always equal an empty object. Does anyone have an idea how to fix that?

To run an expo development client with detox test runner, I used this guide.

Thanks in advance for any ideas.
