React Native HealthKit getDailyStepCountSamples returning undefined or empty array

I'm using react-native-health to create an app to read daily step counts. I have manually added steps on the simulator Health app and the data source is showing my app and all the Health permissions are on but when I try to getDailyStepCountSamples, I get an empty array.

Also, another issue I have is that I need to initiate HealthKit each time before getting the empty array otherwise I get 'undefined'. Once I initiate HealthKit again, it will return 'undefined' AND log 'Steps: []'. Is there something wrong with my code?

import AppleHealthKit from 'react-native-health';    export function useHealthKit({      init = false,      steps = false,  }) {      const PERMS = AppleHealthKit.Constants.Permissions;        const initiate = () => {          let permissions = {              permissions: {                  read: [                      PERMS.StepCount,                  ],              },          };          AppleHealthKit.initHealthKit(permissions, (err, results) => {              if (err) {                  console.log(err);              } else {                  console.log('Initialized!', results),              }          });      };        const getSteps = () => {          let stepOptions = {              startDate: new Date(2021, 1, 1).toISOString(),          };          AppleHealthKit.getDailyStepCountSamples(              stepOptions,              (err, results) => {                  if (err) {                      return;                  }                  console.log('Steps: ', results);              },          );      };      init && initiate();      steps && getSteps();  }  

I call this by doing the following:

const SomeView = () => {      <View>        <Button onPress={() => useHealthKit({init: true})>          <Text>Initiate HealthKit</Text>        </Button>        <Button onPress={() => console.log(useHealthKit({steps: true}))>          <Text>Console.log steps</Text>        </Button>      </View>  };
