};

Report incorrect solution

const anticaptcha = require('anticaptcha-async');

    const client = anticaptcha(process.env.ANTICAPTCHA_KEY);

    const result = await client.getImage(fs.createReadStream('captcha_ms.jpeg'));
    if(result.getValue() !== '56nn2'){
        await result.reportIncorrect();

};

Custom tasks
