I tried uploading a video to Twitter via Chunked Uploading using the Twit npm librarym https://www.npmjs.com/package/twit and all I keep getting back is this error:

allErrors: [ { code: 324, message: 'Pre-processing has not been done for this video' } ]

Here is my code:

let T = new Twit({
    consumer_key: oAuthConsumerKey,
    consumer_secret: oAuthConsumerSecret,
    access_token: access_token,
    access_token_secret: access_token_secret,
    timeout_ms: 60 * 1000,
    strictSSL: true,
});

let filePath =...;

T.postMediaChunked({ file_path: filePath }, function (err, data, response) {
    fs.unlink(filePath, () => { }); //Delete File
    if (data) {
        let mediaIdString = data['media_id_string'];
        let { error } = await T.post('media/metadata/create', metaPrams);
        if (error) {
            throw error;
        }
        //If we got here, then no errors.Cool
        let mediaIds = [];
        mediaIds.push(mediaIds);
        //And then I post the status here
        let params = { status: bodyText };
        params['media_ids'] = mediaIds;
        let { error, data } = await T.post('statuses/update', params);
        //The error I keep getting back is this
        allErrors: [
            {
                code: 324,
                message: 'Pre-processing has not been done for this video'
            }
        ]
    }
    if (err) {
        throw err;
    }
});

Please, what can I do to resolve this? Thank you.
