❔ Error passing builder.Configuration as argument - .net 7

As you can see I am passing the builder.Configuration as an argument to my ConfigureIdentityServices and AddInfrastructureServices functions. When I run the program the jwtKey variable is null and when I access the IConfigurationSection of the builder.Configuration it has its value. The truth is that I don't know how to explain the situation correctly, so I leave you with images. Can anybody help me? Thank you so much!
