Build failed with an exception

[mhr]

$ yarn android resulted in a build error (below). I double-checked that I had no other error-causing package installed: I ran yarn android before and after installing tzachari/react-native-contact-tracing, and it was a clean build before.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > Android resource linking failed
