I am using expo-error-recovery library. On the App component, if something is wrong, exp is provided. If an error happened in my NavMain or other component, exp is undefined.

const defaultErrorHandler = ErrorUtils.getGlobalHandler();
const globalErrorHandler = (err, isFatal) => {
  console.log("err");
  ErrorRecovery.setRecoveryProps({ info: err });
  defaultErrorHandler(err, isFatal);
};
ErrorUtils.setGlobalHandler(globalErrorHandler);

export default ({ exp }) => {
  if (exp.errorRecovery != null) return <ErrorFallback exp={exp} />;
  return (
    <NavMain />
  );
};
