React - Unexpected token u in JSON at position 5

Question

I'm retrieving data from s3 , I have set the content type as "application/json" for the file. The call is successful. In the network --> response tab i see data as

{
  user: "test"
}

When i call the response.json() , I am getting below Error

index.js:1 SyntaxError: Unexpected token u in JSON at position 5

Answer 1

The problem is exactly what the error message says. That isn't valid JSON.

JSON requires quoted keys :

{
  "user": "test"
}
