[v1.35.0] "io.grpc.StatusRuntimeException: UNKNOWN" Failed to take screenshot on android flow failure #1647

DavidREntwistle · 2024-01-09T11:52:02Z

Describe the bug
When a failure occurs on android, an UNKNOWN exception is thrown when a screenshot is attempted to be taken.

To Reproduce

Environment information (please complete the following information):

Maestro version [v1.35.0]
Platform: [Android 13.0]
Framework: [Native Android]
Device model and OS version: [Pixel]

I believe this is related/causes these issues I've also raised:

[v1.34.0] Android driver unreachable whilst running flow
[v1.33.1] Exception in thread "pool-4-thread-1" java.io.IOException: Command failed (host:transport:emulator-5554): device 'emulator-5554' not found/device offline

I think this issue could be caused by the grpc server (that Maestro starts up inside the emulator vm) not running (when it should). Then the dadb (adb wrapper) fails because there is no network to run the commands on. Found this issue raised for grpc, but more shots in the dark grpc/grpc-java#10120

DavidREntwistle · 2024-01-22T12:53:51Z

I think what happens before this issue is thrown:

An android alert displays "System UI isn't responding" & also a secondary alert "Process system isn't responding".
Running the flow then throws the "io.grpc.StatusRuntimeException: UNKNOWN" error raised above.
Closing these two android alerts displayed & re-running the flow then runs the flow without error.
