Different behaviour when body is missing

Repro steps

given the following function.json

{
  "entryPoint": "handler",
  "bindings": [
    {
      "type": "httpTrigger",
      "direction": "in",
      "name": "req",
      "methods": [ "get" ],
      "route": "embed/{appId}",
      "authLevel": "anonymous"
    },
    {
      "type": "http",
      "direction": "out",
      "name": "$return"
    }
  ],
  "disabled": false
}

and the following handler

export function handler(ctx, req) {
  return Promise.resolve({
    status: 302, headers: { Location: '/new_url' }
  })
}

Expected behavior

redirect to /new_url

Actual behavior

returns status 200, with JSON body: { status: 302, headers: { Location: '/new_url' } }

Known workarounds

adding an empty body causes the redirect to be followed

export function handler(ctx, req) {
  return Promise.resolve({
    body: '', status: 302, headers: { Location: '/new_url' }
  })
}

Is this behaviour intentional? Seems very confusing

@mamaso didn’t realise you can do body: undefined, thanks!

Thanks for clarifying! Would personally prefer it to always treat object as response object, for consistency sake. But don’t think its a major issue either way
