Nullability of reference types in type of parameter 'type' of 'object TypeResolver.Resolve(Type type)' doesn't match implicitly implemented member 'object? ITypeResolver.Resolve(Type? type)' (possibly because of nullability attributes).

Non-nullable property 'Filter' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Dereference of a possibly null reference.

Converting null literal or possible null value to non-nullable type.

Converting null literal or possible null value to non-nullable type.

Non-nullable property 'Name' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'Message' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'Data' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

The result of the expression is always 'false' since a value of type 'DateOnly' is never equal to 'null' of type 'DateOnly?'
