Error while fetching data on playground.

[Lavanyagaur22]

Description

While creating a task using mutation:

mutation {
    createTask(input: {
    version: 1,
    title: "Task 1",
    description: "Hello 1",
    status: "Open"   
  }){
 version
  id
  } 
}  

I got the following error:

{
  "errors": [
    {
      "message": "Cannot return null for non-nullable field Task.id.",
 ...

Why is it returning this instead of returning the id?

[Lavanyagaur22]

Also, what's the command to empty the database?

Also, upon running queries and mutations on the playground, we are getting this:

If we don't get any data back, we would be having problems with inflating data in the app.

@Lavanyagaur22 This is graphback issue. Do you mind dropping this issue text into graphback. I will fix that in our server manually.

@wtrocki @harshithdwivedi If we don't get data back, how we are going to inflate it in app?

[wtrocki]

@Lavanyagaur22 This is because you have made some changes that broke it? I get data back for all queries/mutations.

Feel free to improve server as you wish.

[Lavanyagaur22]

Yeah, was about to close the issue. Getting it now.
