Example "account-without-juggler" does not work (anymore?) with NodeJS 10.10.0
Tried above mentioned example (coming from the official Loopback 4 documentation (https://loopback.io/doc/en/lb4/Repositories.html). Example crashes at runtime with message "Cannot start the app. Error: The key servers.RestServer was not bound to any value." Googling and searching through the Loopback 4 documentation (such as https://loopback.io/doc/en/lb4/Server.html and https://loopback.io/doc/en/lb4/Application.html#servers) didn't help.
