Can't start recording audio due to unhandled promise rejection Id = 0

[vitorrafaelm]

I have a project and when I ran this project I cant record any audio, It works fine on android emulator, but on IOS simulator It just not works at all. Im running this project on a Mac M1.

There is the code that I used to start recording audio on Android emulator and it works well.

`const path = Platform.select({
    ios: `file://${user.uid}.m4a`,
    android: `${dirs.CacheDir}/${user.uid}.mp3`,
  });
const onStartRecord = async () => {
    try {
      if (Platform.OS === 'android') {
        try {
          const grants = await PermissionsAndroid.requestMultiple([
            PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
            PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE,
            PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
          ]);
          if (
            grants['android.permission.WRITE_EXTERNAL_STORAGE'] ===
              PermissionsAndroid.RESULTS.GRANTED &&
            grants['android.permission.READ_EXTERNAL_STORAGE'] ===
              PermissionsAndroid.RESULTS.GRANTED &&
            grants['android.permission.RECORD_AUDIO'] ===
              PermissionsAndroid.RESULTS.GRANTED
          ) {
            // console.log('permissions granted');
          } else {
            // console.log('All required permissions not granted');
            return;
          }
        } catch (err) {
          console.warn(err);
          return;
        }
      }
  
      const audioSet: AudioSet = {
        AudioEncoderAndroid: AudioEncoderAndroidType.AAC,
        AudioSourceAndroid: AudioSourceAndroidType.MIC,
        AVEncoderAudioQualityKeyIOS: AVEncoderAudioQualityIOSType.high,
        AVNumberOfChannelsKeyIOS: 2,
        AVFormatIDKeyIOS: AVEncodingOption.aac,
        OutputFormatAndroid: OutputFormatAndroidType.AAC_ADTS,
      };
  
      await audioRecorderPlayer.startRecorder(path, audioSet);
  
      audioRecorderPlayer.addRecordBackListener((e: RecordBackType) => {
        setRecorderState({
          ...recorderState,
          recordSecs: e.currentPosition,
          recordTime: audioRecorderPlayer.mmssss(Math.floor(e.currentPosition)),
        });
      });
    } catch (error) {
      console.log(error);
    }`

When I try this on IOS simulator I got this error: Possible Unhandled Promise Rejection (id: 0): Error: Error occured during initiating recorder Error: Error occured during initiating recorder at Object.promiseMethodWrapper [as startRecorder

I do not know why it happens, I already execute the following commands as a attempt to make it work

• arch -x86_64 pod deintegrate
• arch -x86_64 pod install
• arch -x86_64 yarn run ios

Debugging this on chrome developer tools I found the error is in the current line of code: return _context.abrupt("return", RNAudioRecorderPlayer.startRecorder(uri != null ? uri : 'DEFAULT', audioSets, meteringEnabled != null ? meteringEnabled : false));

Version of react-native-audio-recorder-player: 3.5.1

Version of React Native: "react-native": "0.67",

Platforms you faced the error (IOS or Android or both?) : just IOS

Expected behavior: initiate the audio record

Actual behavior: It just give me the error: Possible Unhandled Promise Rejection (id: 0): and when I click on the button to stop recording I have another error: LogBox.js:173 Sending rn-recordback with no listeners registered.

I've just tried myself with m1 mackbook air. I could not reproduce this. Help you tried the Example project in the repo?

I got the same error on IOS. Solved it by appending file:// to IOS path.

const path = Platform.select({
    ios: `file://${user.uid}.m4a`, 
    android: `${dirs.CacheDir}/${user.uid}.mp3`,
  });

WARN Possible Unhandled Promise Rejection (id: 0): Error: Error occured during initiating recorder

[Lordhacker756]

[yaonimingsanqian]

[AlkanV]

Hello, any update on this one? I also have same problem

[maitrungduc1410]

it's still happening now.

for some first tries, it works, but then suddenly it says Error occured during initiating recorder without any reason, even deleting app and rerun is not working

[claudiozam]

In my case it was related to the number of channels. Now it works with AVNumberOfChannelsKeyIOS = 2.

Error: Error occured during recording Any One Pls Give Solution for above error i am facing only IOS Platform

[NektariosPapergo]

Same issue for me guys. In the swift file RNAudioRecorderPlayer: 293 if !isRecordStarted { reject("RNAudioPlayerRecorder", "Error occured during initiating recorder", nil) return }

The debugger shows isRecordStarted as false
