I'm trying to send react-native-audio-record to backend but I've no idea what to do next, I get the audio file but when I send it I get it's not a file here's my code

const record = async () => {
        
        console.log("clicked")
        const p = await PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.RECORD_AUDIO);
        console.log(`my permission is ${p}`)
        if (p !== true) {
            await PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.RECORD_AUDIO)
        } else {
            if (!recording) {
                const options = {
                    sampleRate: 16000,
                    channels: 1,
                    bitsPerSample: 16,
                    wavFile: 'test.wav'
                  };

                AudioRecord.init(options);
                setRecording(true)
                AudioRecord.start()
            } else {
                setRecording(false)
                const audioFile = await AudioRecord.stop();
                const formData = new FormData();
                console.log(audioFile)
                formData.append('record', audioFile)
                formData.append('partnerID', partnerID)
                fetch('http://192.168.1.9:5000/messages/', {
                    method: 'POST',
                    body: formData,
                    headers: {
                        'Authorization': `Bearer ${JSON.parse(_access)}`,
                        'Content-Type': `multipart/form-data`
                    },
                }).then((res) => {
                    return res.json()
                }).then((data) => {
                    console.log(data)
                })
            }
        }
    }
