How to use the where clause with IQueryable

I am using Entity Framework Core with reflection to generate some forms dynamically. Everything is working except the WHERE Clause. I get the following error:

An expression tree may not contain a dynamic operation

I am able to fix this by converting my IQueryable to a List, but that introduces different problems that i would like to avoid.

Here is my code:

public async void ViewCollection(PropertyInfo propertyInfo)
{
    Type propertyType = propertyInfo.PropertyType;
    InversePropertyAttribute inversePropertyAttribute = (InversePropertyAttribute)ReflectionHelpers.GetAttribute(propertyInfo, typeof(InversePropertyAttribute));


    //GET THE TYPE OF THE COLLECTION
    Type collectionType = propertyInfo.PropertyType.GenericTypeArguments[0];

    //GET THE INVERSE PROPERTY INFO
    PropertyInfo inverseProperty = collectionType.GetProperty(inversePropertyAttribute.Property);

    //GET THE FOREIGN KEY ATTRIBUTE FROM THE INVERSE PROPERTY
    ForeignKeyAttribute foreignKeyAttribute = (ForeignKeyAttribute)ReflectionHelpers.GetAttribute(inverseProperty, typeof(ForeignKeyAttribute));

    //GET THE FOREIGN KEY PROPERTY FROM THE FOREIGN KEY ATTRIBUTE
    PropertyInfo foreignKeyProperty = collectionType.GetProperty(foreignKeyAttribute.Name);

    //GET INCLUDED TYPE NAMES BY FOREIGN KEY
    IEnumerable<string> includedTypes = collectionType.GetProperties().Where(p => p.PropertyType.IsClass).Where(p => ReflectionHelpers.HasAttribute(p, typeof(ForeignKeyAttribute))).Select(r => r.Name);

    //GET THE DATA SET
    IQueryable<dynamic> items = ReflectionHelpers.GetDbCollectionByType(Db, collectionType);

    //INCLUDE THE INCLUDED TYPES BY NAME
    foreach (string includedType in includedTypes) items = items.Include(includedType);

    //THIS IS WHERE THE ERROR IS
    items = items.Where(i => foreignKeyProperty.GetValue(i, null) == PrimaryKeyProperty.GetValue(Item, null));

    await ShowCollection(collectionType, items, propertyInfo.Name);
}

How can i solve this with out changing my type to a list?
