Question

response = RestClient.post("http://localhost:3000/graphql", default_headers,payload) Because in below method I am using Graphlient::Client which is using a lot of the memory.

  filterLocations(input: $input, first: $first) {
    edges {
      cursor
      node {
       id
       attributes{
