Cannot deserialize value of type `java.lang.String` from Object value about aws-serverless-java-container

[Prajwalgn-07]

And yeah I tried setting the body value to string instead of the json input, and set the header

  "headers": {
    "Authorization": "Bearer <Removed Token>",
    "Content-Type": "application/json"
  }

Then I am getting the HttpMediaTypeNotSupportedException which doesn't make sense

Hey @Prajwalgn-07,
I have tried to reproduce your issue and figure out the cause. In this case I think the issue is with your JSON file, and you were almost on the right path. You need to keep your body value to String instead of json. And you have to set content-type in multiValueHeaders instead of headers, something like mentioned below will work.

"multiValueHeaders":{
    "content-type":["application/json"]
  },

Please set this and let us know if you still get errors.
