I am trying to write a simple query with optional filter params

For example

const query = gql`query FilteredPeople($email: String) {
  people(email: $email) {
    fullName
    email
  }
}`;

I keep getting

"Network error: The inline argument "email" is expected as a variable but was not provided."

It makes me think it’s on the server side, but my schema is pretty straightforward

const RootQuery = `
    type RootQuery {
      people(email: String): [Person]
    }
`;

Looking at the graphql spec to specify if something is optional or not you use a !. As you can see email is not required.

Note I am using apollo client/server and react-apollo. Versions on my 

server
    "graphql": "^0.7.2",
    "graphql-server-express": "^0.4.3",

client
    "apollo-client": "0.5.0",
    "graphql-tag": "0.1.15",
    "react-apollo": "0.5.16",

Am I missing something? I thought I fixed it, but it stopped working so I guess not.

Although it looks like the String is nullable, it actually is if you decide not to pass anything in at all like so:

const query = gql`query {
  people {
    fullName
    email
  }
}`;

However if you do use pass in a parameter like you did in your question, then you must define that variable.

Hope that helps!

After further investigation it seems like this is expected behaviour.

Operation variables must be used when defining an operation.
