Please paste more code, or maybe even better - create a repository with a minimal reproducible code example.

_For future readers_

This may have been due to using an @ObjectType() CompanyData as an @InputType() in the resolver.

See docs for: inputType

[merko30]

Could you help me with this:

@InputType()
class OrderInputType implements Partial<Order> {
  @Field(type => [Item])
  items: Item[];

  @Field(() => Int)
  totalPrice: number;
}

I get Error: Cannot determine GraphQL input type for items

[MichalLytek]

@merko30
Item also has to be an @InputType

[merko30]

How can I declare ObjectType as InputType at the same time ?

For example, I have an order model, it has many products. OrderInput needs to have many products, but it has to be InputType, I tried ProductType implements Product, but it doesn't work.

Please read the docs before asking questions 😉

This error is also triggered when providing ObjectType as argument for a resolver function.

@Arg("argument") argumentInput: Argument

instead of

@Arg("argument") argumentInput: ArgumentInput

where Argument is @ObjectType and ArgumentInput is @InputType

@MichalLytek you should edit your link, looks like typegraphql.ml sends on a "scam" website

Yep! It's sends to "scam" website
