Bug: AppSyncEventsResolver decorators break scope #3973
Description
Expected Behavior
When using the @onPublish and @onSubscribed decorator of the AppSyncEventsResolver the decorated methods should preserve the this scope of the class they belong to.
This way, these methods can continue accessing class properties and methods.
Current Behavior
When applying the decorators the decorated method is no longer bound and this goes to either the instance of AppSyncEventsResolver or undefined, thus preventing from using other class methods/properties.
Code snippet
const app = new AppSyncEventsResolver({ logger: console });
class Lambda {
public scope = 'scoped';
@app.onPublish('/foo')
public async handleFoo(payload: string) {
return `${this.scope} ${payload}`;
}
public async handler(event: unknown, context: Context) {
return this.stuff(event, context);
}
async stuff(event: unknown, context: Context) {
return app.resolve(event, context);
}
}
const lambda = new Lambda();
const handler = lambda.handler.bind(lambda);Steps to Reproduce
