The only entry point named is `apollo schema:download --endpoint=http://localhost:7071/GraphQL schema.json`; start by reproducing it against that endpoint and inspecting the returned introspection response. Determine which part of the CLI reports the `Expected , found Name "of"` error, then define completion as the command handling this response correctly or clearly identifying the incompatible response.
