Getting Timeout error(504) from an https POST endpoint in swagger-ui

Question

I am using POST api built by different team in our application and since its taking more than 1 minute to return a response our graphql mutation is returning Internal_Server_error (https://www.apollographql.com/docs/apollo-server/v2/data/errors#internal_server_error). We are using @types/node-fetch: "1.6.9" to consume these endpoints. I tried to set the timeout in the options object of the request as mentioned in github (https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/node-fetch/index.d.ts#L59) but Apollo server is still giving Internal_Server_Error. I tried using AbortController but our application is currently using Node 12.x.x and abort controller requires node 14.x.x.

I just want to know if there is anything we can do from our end to make apollo server wait for the request to be successful which should take 1 minute and 10 seconds and not give out 504.

This is how I am setting the timeout

   import fetch from "node-fetch";

   const res = await fetch(`${this.baseURL}/api/v1/dummy?${query}`,
     {
      method: "POST",
      body: JSON.stringify({
       -----
       -----
      }),
      timeout: 60000,
      headers: {"Content-Type": "application/json"},
    });

Value of res variable after running the mutation:
