Fix bugs:

Fixed "rule is not a function" when run "npm run relay"
getOperation is not a function

Probably you use a different version of Relay.

Please run the following command and provide your output here:

npm list react-relay

I think that you install packages via npm, but in repo used yarn.
So to avoid this problem I want to update and fix package.json versions.

Thanks.

For me all works as expected when I install packages via yarn install.

You may obtain a working solution when change in package.json the following lines:

- "react-relay": "^1.4.1",
+ "react-relay": "1.4.1",

- "relay-compiler": "^1.4.1",
+ "relay-compiler": "1.4.1",
