I trying to make scanner app for tc21 in react native with module https://www.npmjs.com/package/@nextup/react-native-zebra-scanner.

But I got this:

error Attempt to invoke virtual method
'com.symbol.emdk.EMDKBase
com.symbol.emdk.EMDKManager
.getInstance(com.symbol.emdk.E
MDKManager$FEATURE_TYPE)'
on a null object reference
initBarcodeManager
ZebraScanner Module.java:123
startReader
ZebraScannerModule.java:185
invoke
Method.java

JavaMethodWrapper.java:372

Do you have advice on how to fix it or new approach to take for making a React Native app for a Zebra scanner
