Route url with variable in apolloGateway

Question

There are several services that process graphql-requests on relative URLs. Example: http://service:8080/graphql/a3333333-b111-c111-d111-e00000000011. And I don’t understand how to config apolloGateway that part of url is a variable.

Try config url as:

const test_service: string = 'http://service:8080/graphql/:project';

    supergraphSdl: new IntrospectAndCompose({
        subgraphs: [
            { name: 'test_service', url: test_service },
        ],
    }),

So full service look like:

import { ApolloServer } from 'apollo-server'
import { ApolloGateway, IntrospectAndCompose, RemoteGraphQLDataSource } from '@apollo/gateway'

const test_service: string = 'http://service:8080/graphql/:project';

const gateway_main = new ApolloGateway({
    supergraphSdl: new IntrospectAndCompose({
        subgraphs: [
            { name: 'test_service', url: test_service },
        ],
    }),
});

const server_main = new ApolloServer({
    introspection: true,
    gateway: gateway_main
});

server_main.listen(8060).then(({ url }) => {
  console.log(`Server ready at ${url}`);
});

But if I send a request to url http://service:8060/graphql/a3333333-b111-c111-d111-e00000000011 test_service get it as http://service/graphql/:project So test_service lose uuid-data
