tesseract.js-core 2.2.0 (Tesseract 4.1.1) Whitelist not working

[Marc-K-Plewka]

Hello,
I was just trying to get the whitelist option setup with the scheduler. I already read the issues regarding the whitelist problem in Tesseract 4.0, but it should be fixed in version 4.1 and upwards. So my question is, how do I get the whitelist working again with the scheduler. Thanks in advance.

My current approach looks like this:

`

  //worker and scheduler setup called on start 
  (async () => {

                    try {
                        var basePath = path.join(__dirname,'../');
                        for (i = 0; i < 4; i++) {
                            var worker = createWorker({ langPath: basePath});
                            await worker.load();
                            await worker.loadLanguage('deu');
                            await worker.initialize('deu');
                            scheduler.addWorker(worker);

                        }
                    }
                    catch (err) {
                        console.log(err);
                    }
                })();

    //actual tesseract request called on file upload request
    //in reality I have a switch here to set different whitelists based on the incoming file
    let options = { tessedit_char_whitlist: '0123456789' };
    (async () => {
                    try {
                        const { data: { text } } = await scheduler.addJob('recognize', filePath, options);
                        console.log(text);
                        textRes = text;
                        res.send(textRes);
                    }
                     catch (ew1) {
                        throw ew1;
                    }
                })();

Closing as the master branch of tesseract.js-core was updated to use Tesseract 5, which does not have this issue (naptha/tesseract.js-core#18).
