Boarding Pass has my last name and first name swapped. Should I call to get it fixed before going or will it not matter?

Basically as the title says. I booked this through Expedia a few months ago and my flight is in the morning, so when I was doing check in I noticed that they had my last and first name swapped when I put the trip on the United App. Is this gonna be an issue? I don't really fly United so wasn't sure if it was something to worry about or not.
