If you encounter an error like `Cannot query field "node" on type "Query"`, you most likely forgot to add the `node` Field.
## Mutations
Most APIs don't just allow you to read data, they also allow you to write. In GraphQL, this is done using mutations. Just like queries, Relay puts some additional requirements on mutations, but Graphene nicely manages that for you. All you need to do is make your mutation a subclass of `relay.ClientIDMutation`.
