ASP.NET why aren't model entries returned?

Question

ASP.NET

As you can see from the screenshot, the query returns zero records (the lowest variable partners = null), but at the same time they exist and are marked in local. What could be the problem? There is a client completely similar, but there returns 7 records.

Answer 1

Naturally, it will be null there, since the break point is triggered first, and then the Partners.ToList() method will be executed.
Take a step forward - then it will not be null, but an empty list, for example.
If an empty list confuses, then there is no data in the database, or a curved mapping is done
