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

The fix for this turned out to work by treating the dialog field as a string instead of an object. Changing the function to this did the trick and made the errors go away:

  openDialog: (_, variables, { cache }) => {
    const data = {
      popups: {
        ...popups,
        dialog: variables.type
      }
    };

    cache.writeData({
      data: data
    });
    return null;
  }
