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

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

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

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

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

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