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

Answer to the actual problem seems lay in the query. Initially Apollo client was not validating types for @client queries/mutations so your mutation could look like you wrote it in the question:

mutation AlertOpenDialog($type: String!) {
  openDialog(type: $type) @client
}

the correct way of writing above is to specify (select) all the simple type (scalar) fields you wanna get in a response. So in regard to the @Vic answer the mutation should look more like:

mutation AlertOpenDialog($type: String!) {
  openDialog(type: $type) @client {
    dialog {
      id
    }
  }
}
