Загрузка автономных данных lang в tesseract.js

Я пытаюсь загрузить свои собственные подготовленные данные в tesseract.js. Когда файл размещен локально, я попытался загрузить все в автономном режиме. Код, который я использовал, показан ниже:

<script src="tesseract.js"></script>

<script>
//Set the worker, core and lang to local files
(function() {
var path = (function() { //absolute path
    var pathArray = window.location.pathname.split( '/' );
    pathArray.pop(); //Remove the last ("**.html")
    return window.location.origin + pathArray.join("/");
})();
console.log(path);

window.Tesseract = Tesseract.create({
    workerPath: path + '/worker.js',
    //langPath: path + '/traineddata/',
    corePath: path + '/index.js',
});
})();
</script>

<script>
function recognizeFile(file){
    document.querySelector("#log").innerHTML = ''

    Tesseract.recognize(file, {
        lang: document.querySelector('#langsel').value
    })
        .progress(function(packet){
            console.info(packet)
            progressUpdate(packet)

        })
        .then(function(data){
            console.log(data)
            progressUpdate({ status: 'done', data: data })
        })
}
</script>

Приведенный выше код работает нормально, если langPath не установлен, но когда я указываю langPath в локальную папку, Tesseract не смог загрузить что-либо со следующей ошибкой:

Failed loading language 'eng'
Tesseract couldn't load any languages!

У меня есть как eng.traineddata, так и eng.traineddata.gz в папке /trainingdata, поскольку, по-видимому, процесс ungzip пропускается. Есть ли что-то, чего я пренебрегал? Любая помощь приветствуется.
