## Problems
|
||||
|
||||
1. Setting type directly on field:
|
||||
|
||||
```js
|
||||
fields: ()=>{
|
||||
username: GraphQLString
|
||||
}
|
||||
```
|
||||
|
||||
threw this error:
|
||||
|
||||
```sh
|
||||
Unhandled rejection Error: Query.viewer field type must be Output Type but got: undefined
|
||||
```
|
||||
|
||||
Must pass object:
|
||||
|
||||
```js
|
||||
fields: ()=>{
|
||||
username: {
|
||||
type: GraphQLString
|
||||
}
|
||||
}
|
||||
```
