Datastore - Typescript - Predicates

[mlecoq]

Hi,

I am using Create React App with typescript template.

When I write this line:

const posts = await DataStore.query(Post, Predicates.ALL);

I have the following error:

No overload matches this call.
  Overload 1 of 2, '(modelConstructor: PersistentModelConstructor<Post>, id: string): Promise<Post>', gave the following error.
    Argument of type 'ProducerModelPredicate<any>' is not assignable to parameter of type 'string'.
  Overload 2 of 2, '(modelConstructor: PersistentModelConstructor<Post>, criteria?: ProducerModelPredicate<Post> | undefined, pagination?: PaginationInput | undefined): Promise<...>', gave the following error.
    Argument of type 'ProducerModelPredicate<any>' is not assignable to parameter of type 'ProducerModelPredicate<Post>'.
      Types of parameters 'condition' and 'condition' are incompatible.
        Type 'ModelPredicate<Post>' is not assignable to type 'ModelPredicate<any>'.
          Type 'ModelPredicate<Post>' is not assignable to type '{ [x: string]: (operator: never, operand: never) => ModelPredicate<any>; }'.
            Index signature is missing in type 'ModelPredicate<Post>'.ts(2769)

I have to write

const posts = await DataStore.query(
        Post,
        (Predicates.ALL as unknown) as ProducerModelPredicate<Post>
      );

@mlecoq which typescript version are you using?

[mlecoq]

@mlabieniec typescript 3.7.5

@mlecoq We do have our Typescript version set to 3.6.4. Can you verify if using this Typescript version will resolve your issue?

[mlecoq]

@sammartinez I have tried with 3.6.4, and unfortunately I have the same error

I am also facing the same problem. I am using Typescript 3.7.5 and don't want to downgrade

@mlecoq thanks for workaround solution

React has new update 16.13 that comes with Typescript 3.8.2

So eventually will require support for Typescript 3.8.2
