Missing selection set for object GraphQL+Apollo error

Question

I have a set of mutations that trigger the local state of certain types of popups. They\'re generally set up like this:

  openDialog: (_, variables, { cache }) =         


        

Answer 1

Solution is to add fields to the query (vs. declaring the top-level object you want to fetch without specifying the fields to fetch). If you have something like:

{
  popups @client {
    id
    dialog
  }
}

you must declare some fields to fetch inside dialog, for example id:

{
  popups @client {
    id
    dialog {
      id
    }
  }
}
