Manipulate context and add dynamic header value on the fly in custom resolver

[mnlbox]

Hi guys,

I have a custom resolver that uses mesh SDK to combine two services in a new resolver. So I can call this custom resolver findUserGroups and inside this resolver implementation, I'm using two SDK functions to findUser based on email and get the id for the user and I want to pass this id as a request header to the second API call. The second one is another SDK function called findGroup each SDK functions belongs to different sources and different GraphQL subgraphs.
How can I manipulate and modify context inside the custom resolver and pass this new context to the SDK?

My resolver is something like this:

import {
  FindUserResult,
  FindGroupResult,
  Resolvers,
} from "../.mesh";

const resolvers: Resolvers = {
  Query: {
    findUserGroups: async (root, args, context, info) => {
      // @ts-ignore
      const apiKey = context.headers["api-key"];
      // @ts-ignore
      const role = context.headers["role"];

      // 1. Check the required headers
      if (!apiKey || !role) {
        throw new Error(
          "api-key and role are mandatory"
        );
      }  
      
      const findUserResult: FindUserResult =
        await context.User_API.Query.findUser({
          root,
          args,
          context,
          info
        });

        const userId = findUserResult[0].id;
        console.log(userId)        

        const findGroupResult: FindGroupResult =
        await context.Group_API.Query.findGroup({
          root,
          args,
          context,  <-------------------- I need to pass "userId" here to this SDK call
          info
        });
      
    }
  }

In fact, for findGroup query I need to pass 3 header values. I have to pass apiKey and role from the main request and add userId to that from the result of findUser API call.
