ASP.NET API Controller not returning values shown in debugger

I am attempting to return a list of chores when the user queries an endpoint

/Chores?page=1&pageSize=10

/Chores?page=1&pageSize=10

. This endpoint takes the user's claims and pulls a list of that users chores, paginating them as requested. This seems to work fine from the debugger, with the Controller showing 10 chores (a full page) and a total chore count of 26 (see image 1) being returned as a JsonResult. However, the response I receive when querying this endpoint via Swagger UI is an empty object

{}

{}

(image 2), even though the response is 200 and I know the controller function returned valid data.

What could be causing my controller to return a blank value, even when the debugger indicates it is returning valid data?
