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

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 {} 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.

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.

Help appreciated to solve this problem.

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 -
