There should be a comma right after weekend.
We're not sure if the tickets are for the preview night, the opening night, this weekend, or next week.
Hope this helps you.

The answer to your question would be that what best describes the punctuation error in the sentence is that a comma should be placed after "this weekend". The use of the comma shown in the sentence is the Oxford comma.
An Oxford comma, also called serial comma, is a comma used before the last item in a list of three or more items. When there are three or more items, then you should use a comma with the conjunction (and/or).
