I didn’t deliver drinks, what do I do?

I was doordashing and then I got a $13 for 4 miles offer so I took it. It was like 3 bags of food. The app didn’t tell me the items that were in the bags, which is rare but I’m sure you’ve all had an order like that before. When I delivered the order, they told me they were missing two sprites. What should I do in that situation if it happens again? I told them to call the restaurant because I wasn’t informed that there were drinks with this order. Am I in the wrong?
