I wonder if it has to do with this: https://github.com/hieuvp/react-native-fingerprint-scanner/blob/31f160f6437415258a6204ca8481612b314e41f8/android/src/main/java/com/hieuvp/fingerprint/ReactNativeFingerprintScannerModule.java#L98-L101

The way all the biometric stuff works changed with android API28 (Android P) and you don't specify what device under test is running, this guess is for >= 28

I could not find any relevant issues on stackoverflow which is usually an indicator that platform API usage is incorrect, stated differently - the code here may not be 100%, you might be on to something
