Yes, I noticed that as well, however, that was not the source of the error for me, at least. I actually changed that to $self->id but the error was the same. Empty $self->id.

I am going to release it to CPAN. I have just sat on it all this while, but this is a good incentive to fix it and release it. The git repo is at https://github.com/punkish/Dancer--Session--SQLite
