dynamic endpoint not working

[MM3y3r]

Hi. I cannot seem to get to work the dynamic endpoint with my meshrc :

    handler:
      graphql:
        endpoint: "{env.MAIN_API_GRAPHQL_URL}/graphql"

The above should work, but it does not. For context here is my yoga server which uses mesh.

import { createServer } from '@graphql-yoga/node';
import type { ServeMeshOptions } from '@graphql-mesh/runtime';

export default async function ({
	getBuiltMesh,
	logger,
	argsPort = config.PORT,
}: ServeMeshOptions): Promise<void> {
        const { schema, getEnveloped } = await getBuiltMesh();

	const server = createServer({
		schema: schema,
		graphiql: process.env.NODE_ENV !== 'production',
		port: argsPort,
		plugins: [getEnveloped],
		endpoint: '/graphql',
		logging: true,
		maskedErrors: process.env.NODE_ENV === 'production',
	});

	await server.start();
}

How can i access "{env.MAIN_API_GRAPHQL_URL}/graphql" in the meshrc file ?

@ardatan does the sandbox need to run? https://codesandbox.io/embed/graphq-mesh-with-yoga-u8zrzz

This is working fine for me with the following query;

{
  allFilms(first: 2) {
    films {
      id
      title
    }
  }
}

Few tips;
You need to pass plugins not getEnveloped to Yoga.
You don't need explicitly download your schema which mesh build does this already.
schema.graphql file doesn't have a Query type which is needed for every single GraphQL Schema.
You don't need a custom server with Yoga since Mesh already uses Yoga. If you want to extend the context, you can use useExtendContext envelop plugin with the existing Mesh server.

How would I create custom routes for health checks with the mesh server? Does it have the same ones as yoga?

Thanks for the extensive answer by the way. I will try without yoga now. Thank you!!!

Yes https://github.com/Urigo/graphql-mesh/blob/master/packages/cli/src/commands/serve/serve.ts#L216

Just FYI in my case the problem originated with docker/kubernetes and was therefore unrelated to this tool. Be aware that env vars are not available during build step.
