Unable to infer GraphQL type from TypeScript reflection system

[AlexanderFagrelius]

Hello!

I am trying to add "motorid" to the accessory mutation so i can add it to the joined table on the MySQL database via Apollo server but i am getting the error Unable to infer GraphQL type from TypeScript reflection system. You need to provide explicit type for argument named 'motorId' of 'Accessory' of 'AccessoryResolver' class.

The Accessory entity and modules

The Motor entity and modules

@Arg("motorId", () => [Motor])

And what is your error when you have @Arg("motorId", () => [Motor]) motorid: Motor[]?

[AlexanderFagrelius]

i get UnhandledPromiseRejectionWarning: Error: Cannot determine GraphQL input type for argument named 'motorId' of 'Accessory' of 'AccessoryResolver' class. Is the value, that is used as its TS type or explicit type, decorated with a proper decorator or is it a proper input value?

[MichalLytek]

So have you checked, accordingly to the error, if Motor class has @InputType decorator?

I think you need to start with reading the docs. Then you will understand why you need input types and object types.

The Motor class is a @ObjectType. Feels like i've read the docs a million times, but i will read it again. Thanks for trying to help atleast 😄
