Unable to cast object of type 'LiteDB.ObjectId' to type 'System.String' about zlocation HOT 3 OPEN

@cspotcode do you know where that may come from?

from zlocation.

@vors, no I'm not sure, except it seems like somewhere we're accidentally putting a nonsense entry into the database. Maybe we're passing an incomplete object to the $mapper somewhere? Like, what happens if we accidentally try to increase the weight for a path when no such path entry exists in the database? Just a guess.

Now that I think about it for a few more minutes, I suspect that's the problem. I suspect that somewhere we're calling Add-ZWeight or $service.add() with a null $path. We have the Location class's path field mapped as LiteDB's _id. (LiteDB makes _id mandatory; otherwise I would have named it path within the database) So if $path/_id is unspecified, the database will auto-create an ID for that row, except the auto-created IDs aren't strings. Later, we try to map that row to a [Location] instance, and it fails because it can't convert the _id to Location's path field.
