Check Engine light on in a Mercedes B-Class

Hello everyone, I have a 2017 Mercedes B-Class with a gasoline engine and 63,700 km mileage. Recently, the check engine light has come on. Does anyone have experience with this problem or can give me tips on what the cause might be and how I can fix it? Thanks in advance!
