Variable is not in scope error when relay-compiling Relay Modern code

Question

I have the following simple Relay Modern code:

import React, { Component } from 'react';
import PropTypes from 'prop-types';

import {
    QueryRenderer,
    graphql
} from 'react-relay'


import environment from '../../../../../environment'

const CompanyItemQuery = graphql`

query CompanyItem_Query {
  node(id: $companyId) {
    id
    ...on Company {
      id
      name
    }
 }
}
`

class CompanyItem extends Component {

    render() {

        return (
                <QueryRenderer
                    environment={environment}
                    query={CompanyItemQuery}
                    variables={{
                        companyId: 'test',
                    }}
                    render={({error, props}) => {
                        <div>
                            <p>Relay loaded {props.name} company</p>
                        </div>
                }}
                />
        );
    }
};

export default CompanyItem;

I'm trying to relay-compile the code before running and I'm getting the following error:

> relay-compiler --src ./src --schema ./src/data/schema.graphql

HINT: pass --watch to keep watching for changes.
Parsed default in 0.08s

I can't find out why my variable companyId is not in scope, as it is defined in the variables section of the QueryRenderer as stated in the documentation.

If I use a fixed value for id (example node id: "Company:59b2cda12504b914cc398100") code is relay-compiled and I can get my data fetched normally. The problem arises when I need to choose the id dynamically.

It looks like you missed declaring the variable (and type) in the query name - so this:

query CompanyItem_Query($companyId: ID!) {

instead of this:

query CompanyItem_Query {

You can see more context in the example on the relay site - https://facebook.github.io/relay/docs/query-renderer.html
