Answer 1

I believe this has to do with the test that you are sending to AWS Lambda. You are sending the default request most likely as when I did that I got the same error. Try testing your application using apollo client.

There is a breaking change in the apollo server. You need to write the file uploads line. https://github.com/apollographql/apollo-server/blob/main/CHANGELOG.md#v230
