Platform(s)

I tested only in android.

Current Behavior

I created a new app using capacitor 3, in this app I tried to use the capacitor run.

When usign the command ionic capacitor run android -l --external to run my app, the console returns:

Which device would you like to target? (Use arrow keys)
And nothing appears in console, if I type "Enter", this message is show:
TypeError: Cannot read property 'value' of undefined

Expected Behavior

Open app in a device

Code Reproduction

ionic capacitor run android -livereload --external

Other Technical Details

I tried install @ionic/cli@testing as mentioned in THIS ISSUE, but didn't work. The only way to test my app is using ionic cap build android, but it is very time consuming.

I also tried to use ionic capacitor run android -l --address=myIp, as mentioned in Ionic Forum, but this didn't work either.

npm --version output: 6.14.12

node --version output: v14.16.1

the problem is the same as #4571

capacitor run command searches for connected devices and configured emulators, but for some reason it's not finding yours, so shows an empty list

I had the same issue, using this command resolve it:
ionic capacitor run android -l --external --open
