Apollo Server 3 - doesn't work

[nova93]

Bug Report

Brand-new project created today (28th July 2021), using the starter script (https://www.apollographql.com/docs/apollo-server/deployment/lambda/). Nothing added, not even middleware, doesn't work locally at all, with no errors showing in the console.

Current Behavior
locally npm run dev:
GET: Cannot GET null (404)
POST (through Postman): Cannot POST null (404)

deployed
works just fine, as expected

Sample Code
https://github.com/nova93/apollo-3-test

Expected behavior/code
Expect the deployed version to work the same locally (in this case, a landing page linking to Apollo Sandbox), and Postman queries to return the same as deployed (in this case Hello world!)

Environment

• serverless version: 2.52.1
• serverless-offline version: tried latest 8.0.0 and 7.1.0, same story
• node.js version: v14.17.1
• OS: macOs 10.15.7 Catalina

Possible Solution

I believe it might be something with the total rewrite of AS3, and their use of the 3rd party package to convert Lambda to Express-type requests.
This thread talks about their changes, and decisions: apollographql/apollo-server#5415

Same Issue for me, I think this issue is about default URL.
I've made change in serverless.yml file by changing default url path by something else like path: /graphql.
Now all work for me, locally and deployed.

before:

- http:
          path: /
          method: post
          cors: true

after:

- http:
          path: /graphql
          method: post
          cors: true

I hope this help you solve your issue
