Description

I tried to record audio using the steps in the documentation, but the app crashed.

Assertion failed: (isString()), function getString, file jsi.h, line 1561.

Steps to reproduce

1. Install react-native-audio-api
2. Configure expo plugins:

{
  "plugins": [
    [
      "react-native-audio-api",
      {
        "iosBackgroundMode": true,
        "iosMicrophonePermission": "This app requires access to the microphone to record audio.",
        "androidPermissions" : [
          "android.permission.RECORD_AUDIO",
          "android.permission.FOREGROUND_SERVICE",
          "android.permission.FOREGROUND_SERVICE_MICROPHONE",
        ],
        "androidForegroundService": true,
        "androidFSTypes": ["microphone"]
      }
    ]
  ]
}

3. Create a demo page:

import React, { useState } from 'react';
import { View, Pressable, Text } from 'react-native';
import { AudioRecorder, AudioManager } from 'react-native-audio-api';

AudioManager.setAudioSessionOptions({
  iosCategory: 'record',
  iosMode: 'default',
  iosOptions: [],
});

const audioRecorder = new AudioRecorder();

// Enables recording to file with default configuration
audioRecorder.enableFileOutput();

const MyRecorder: React.FC = () => {
  const [isRecording, setIsRecording] = useState(false);

  const onStart = async () => {
    if (isRecording) {
      return;
    }

    // Make sure the permissions are granted
    const permissions = await AudioManager.requestRecordingPermissions();

    if (permissions !== 'Granted') {
      console.warn('Permissions are not granted');
      return;
    }

    // Activate audio session
    const success = await AudioManager.setAudioSessionActivity(true);

    if (!success) {
      console.warn('Could not activate the audio session');
      return;
    }

    const result = audioRecorder.start();
    if (result.status === 'error') {
      console.warn(result.message);
      return;
    }

    console.log('Recording started to file:', result.path);
    setIsRecording(true);
  };

  const onStop = () => {
    if (!isRecording) {
      return;
    }

    const result = audioRecorder.stop();
    console.log(result);
    setIsRecording(false);
    AudioManager.setAudioSessionActivity(false);
  };

  return (
    <View>
      <Pressable onPress={isRecording ? onStop : onStart}>
        <Text>{isRecording ? 'Stop' : 'Record'}</Text>
      </Pressable>
    </View>
  );
};

export default MyRecorder;

Hi, it is a bug on our side, quick workaround while we are fixing the issue would be to replace calling

Recorder.start()

to

Recorder.start({
   fileNameOverride: `my_name_${Date.now()}`,
});
