Title: downgrade log message for when invalid url is requested from .error() to .info()

we reserve `.error()` for fatal or unexpected conditions. Because anyone on the internet can request a bogus url, it's not really a big deal, just a silly robot (or human).

Just as HTTP `500` errors are a sign of something wrong with our software, so are errors in logs.
