Detox: Could not find 'undefined' on the currently ADB attached devices: issue even though the device is connected

[MahadevG]

I have created Detox setup in Ubuntu 18.04 .Currently the build is happening fine with the command detox build but while running the detox test command i am getting following error.

Running command
detox build -c android.emu.debug && detox test -c android.emu.debug

The physical device is connected and when i execute adb devices command i could see result as

* daemon started successfully
56149225    device

[chriswiesner]

was currently struggling with the same issue:
If it's a connected device then you need to use adbName instead of avdName in the device config.

edit: docu is lacking that information

[noomorph]

@chriswiesner , it has this information:

https://github.com/wix/Detox/blob/master/docs/APIRef.Configuration.md

[noomorph]

Any actual suggestions, guys?
What a dream product would do in your situations to help you figure out what's wrong?
@MahadevG , @chriswiesner , @Rubenvdveen, @fralyx?

Currently, the formulation of the issue does not suggest any development vector, just a yelp for a help, so to say.

[Rubenvdveen]

@noomorph Maybe add it to the hint in the error message? Or just create a general name for both configurations?
I used these docs for Android setup: https://github.com/wix/Detox/blob/master/docs/Introduction.Android.md#5-add-android-configuration
There is no example of "adbName". It states this:

android.attached. Connect to already-attached android device. The device should be listed in the output of adb devices command under provided name. Use this type to connect to Genymotion emulator.

Which does not tell me to change the device configuration to "adbName" instead of "avdName"
