Shopify GraphQL Returns empty response

[kacalica]

I am trying to just get some data back from the Storefront API using GraphQL. For some reason, I get an empty response. I am using Postman but I will be posting the generated cURL code it gives. 

curl -X POST \
  http://test-store-calica.myshopfiy.com/api/2019-07/graphql \
  -H 'Accept: */*' \
  -H 'Accept-Encoding: gzip, deflate' \
  -H 'Cache-Control: no-cache' \
  -H 'Connection: keep-alive' \
  -H 'Content-Length: 105' \
  -H 'Content-Type: application/graphql' \
  -H 'Cookie: __tad=1567709864.5364039' \
  -H 'Host: test-store-calica.myshopfiy.com' \
  -H 'Postman-Token: 43bb893e-3fdf-484f-9487-4401dec68b00,e33699c1-4619-4a49-ac51-2b7ff3517bb3' \
  -H 'User-Agent: PostmanRuntime/7.15.2' \

  -H 'cache-control: no-cache'
  -d '{
        products {
          edges {
            node {
                id
                title
                }
             }
         }
      }'

I have tried simple queries like: 

{
  shop {
    name
  }
}

Still empty response
