I have one issue to use @InputType of nestjs/graphql

[mystic jay]

I defined the inputType like this.

@InputType()
export class CreateTaskInput {
@Field()
userId: string;

@Field()
name: string;
}

.... resolver file
@Mutation({name: "createTask"})
async createTask(
@Args("taskPayload") taskPayload: CreateTaskInput
) {
  console.log(JSON.stringify(taskPayload), taskPayload.userId); // {} undefined
}

---
mutation CreateTask($payload) {
 createTask(taskPayload: $payload)
}

... CreateTask({taskPayload: { userId: "Test", name: "test" }})

How can I resolve this undefined issue?

Are you using the ValidationPipe?

[mystic jay]

Yes

[sleek lance]

Do you have whitelist: true set in its options?

[mystic jay]

Yes

app.useGlobalPipes(
    new ValidationPipe({
      whitelist: true,
    }),
  );

[sleek lance]

That's the issue then, as that will strip any unknon properties

And by unknown, I mean unknown to class-validator (not decorated with a c-v decorator)

If you don't need validation and just need the property, use @Allow()

[mystic jay]

Where should I add @Allow()? 🙂

[sleek lance]

On each property you want to allow witthout validation

[mystic jay]

Awesome!

Let me try to add it to each property

[sleek lance]

This is class-validator's functionality, and you should refer to their documentation for it

[mystic jay]

Wow. it is working

Thank you @sleek lance
