We do not seem to return a proper gRPC status code in similar code paths either, so I copied the pattern. Not sure if good or not, my expectation/hope would be that gRPC maps this to a generic "internal error" or similar.
@adamwg you may know this one better than me.

I believe the go gRPC framework wraps non-gRPC errors from RPC handlers using the Unknown status code. I always prefer to return explicit gRPC errors with appropriate codes from handlers, but gRPC is OK with it either way.
Makes sense to follow the general pattern here, and if we want to return explicit Internals everywhere we can do that in a separate PR.

Makes sense to me -- will keep that in mind for a follow up PR.

We previously continued processing when fetching the snapshot failed for errors other than 404.
