What to do if not enought PBI to fill a sprint in Scrum

We have an scenario when, at the ending of a proyect there isn't not enought story points to fill a 2 weeks sprint based on the velocity of the team.

The average velocity of the development team is actually 40 points per sprint, but in the product backlog there are just 20 points to be completed.

Should we start the sprint with two weeks, no matter the amount of points; or just make a quick 1 week sprint in this case?
