It’s either an adjusting issue, or a compatibility issue. I’d check first for compatibility. What is the brand of your derailleur, how many speeds does this cassette has, and what’s the tooth count on the largest cog ?

Short cage rear derailleur so officially supports up to a 28t cassette, you might be able to fit more depending on a combination of things.
Start by screwing in the b tension screw untill there is a small gap and the rear derailleur doesnt jump when shifting up.

Too close, usually you want ~5mm gap there, but it depends on the make and model. Needs more B tension (the other screw on your derailleur that’s not high and low limit) or the cassette is too big, probably B tension.

Maybe the chai is too long.
