Is this related to another service?

Lambda

Describe the feature you'd like to request

I want to be able to set cookies in my lambda resolver. This would help me store secure, HTTP-only cookies.

Describe the solution you'd like

I want to set cookies in the lambda function like
`
exports.handler = async (event, context, callback) => {

const response = {
headers : {
"Set-Cookie" : [example-cookie=value]
}
}
callback(null, response)

and the set cookie must be available as the response header of the Graphql HTTP call from the client.

Describe alternatives you've considered

Tried to set the cookie client-side, but it is an insecure solution.

Hi got a similar issue,

Here is my testing experience.

I set up a nginx server locally with the same domain as AppSync endpoint like ".amazonaws.com" to host a front end react app locally. I am using the "$util.http.addResponseHeader("Set-cookie", xxxx-yyyy)" in the VTL resolver, however, I CANNOT see it in the response header while call the api, therefore, not cookie stored in the browser.
