Mocked method isn't called

I have test method and it fails on calling mocked method.

The mocked interface:

public interface IRepository
{
    Documents GetDocuments(
        int projectPK,
        int? folderPK,
        bool useFolders,
        string search,
        int user,
        int page, 
        int pageSize,
        string customerConnectionString);
}

And this is the setup and call of mocked method:

Mock<IRepository> repositoryMock;
repositoryMock
    .Setup(
        c => c.GetDocuments(
                It.IsAny<int>(),
                It.IsAny<int?>(),
                It.IsAny<bool>(),
                It.IsAny<string>(),
                It.IsAny<int>(),
                It.IsAny<int>(),
                It.IsAny<int>(),
                It.IsAny<string>()
            )
    )
    .Returns(new Documents());

After setting strict mode I've found out the source problem is not called and if I try to verify the call like this:

repositoryMock.Verify(
    r => r.GetDocuments(1, 1, true, "", 1 ,1 ,1 , ""));

I get Moq.MockException: Expected invocation on the mock at least once, but was never performed: r => r.GetDocuments(1, (Nullable'1)1, True, "", 1, 1, 1, "")

Does anyone see any mistake I could have made?
