I have this code generated by cdk cli(typecript-language):
import { Stack, StackProps } from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as appsync from '@aws-cdk/aws-appsync';
export class BookStoreGraphqlApiStack extends Stack {
constructor(scope: Construct, id: string, props?: StackProps) {
super(scope, id, props);
const api = new appsync.GraphqlApi(this, 'MyApi', {
name: 'my-book-api',
schema: appsync.Schema.fromAsset('graphql/schema.graphql')
});
}
}
And I get this error:
Argument of type 'this' is not assignable to parameter of type 'Construct'.
Type 'BookStoreGraphqlApiStack' is missing the following properties from type 'Construct': onValidate, onPrepare, onSynthesize

You are mixing dependencies from CDK V1 and the newly released CDK V2, which are incompatible.
To get a valid V2 setup, change the AppSync package to import * as appsync from '@aws-cdk/aws-appsync-alpha'
. In V2, alpha
APIs have separate packages, stable ones are in a common aws-cdk-lib
. AppSync's L2 constructs are in the alpha category.
Here is an overview of import patterns for both CDK versions:
// V2
import { Construct } from 'constructs'; // construct is in a separate package
import { Stack, StackProps, aws_s3 as s3 } from 'aws-cdk-lib'; // common package for stable construct
import * as appsync from '@aws-cdk/aws-appsync-alpha' // alpha constructs in separate packages
// V1 - separate packages core and for each service
import * as cdk from '@aws-cdk/core';
import * as appsync from '@aws-cdk/aws-appsync';

Turns out this is a known problem with aws-cdk, since v2 isn't properly migrated, the solution is:
npm un -g aws-cdk
npm i -g [email protected]
