graphql-subscriptions

I'm planning to use AWS Appsync to migrate a graphQL endpoint in a lambda function, which is being triggered by a POST via the API Gateway. I'm looking into AppSync mainly because of the subscriptions, which I can't create using a Lambda function. My Authentication mechanism is based on Auth0, using passwordless, and my authorization mechanism in based on the data from several tables in DynamoDB and it's embedded in the graphQL resolvers, as recommended by Facebook and Apollo. What is more, it is based on every part of the request, which includes checking permission to invoke the query

I can't seem to understand the error I am getting on my client application. I am subscribing to a graphql subscription and I am able to retrieve the updates but I am not being able to push the changes to the typescript array called "models:ModelClass[]" which is bound to the view. Is there something I am missing or doing wrong? models.component.ts this.apollo.subscribe({ query: gql` subscription { newModelCreated{ _id name type train_status deploy_status data_path description created_at updated_at } } ` }).subscribe((data) => { console.log("CREATED: " + JSON.stringify(data.newModelCreated));
