SignatureDoesNotMatch error when uploading video from React native to AWS Signed url

I'm trying to upload a video to an S3 Signed url generated from Brightcove. The code I have works in Android but not on the iPhone, where it returns:

<?xml version="1.0" encoding="UTF-8"?><Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided.

This is my code:

    const preSignedURL ='XXXX';    let imagePATH = p.node.image.uri;    if (Platform.OS === 'ios') {        const photoPATH = convertLocalIdentifierToAssetLibrary(            p.node.image.uri,'MP4',        );        const dest = `${RNFS.TemporaryDirectoryPath}influencer-2.mp4`;        imagePATH = await RNFS.copyAssetsVideoIOS(            photoPATH,            dest,        );    }    const headers = { 'Content-Type': 'video/mp4' };    imagePATH = imagePATH.replace('file://', '');    RNFetchBlob.fetch('PUT',        preSignedURL,        headers,        RNFetchBlob.wrap(imagePATH),    )        .then((res) => {            const { status } = res.info();            console.log(res.info());            console.log(res.text());            console.log(res.base64());            if (status === 200) {                console.log(res.text());            } else {                // handle other status codes            }        })        // Something went wrong:        .catch((errorMessage, statusCode) => {            console.log(errorMessage);        });}}  

I've tried also using xhr or fetch, but I always get the same error. I understand that the issue might be to a different headers or something else, but this works perfectly in Android
