AWS AppSync subscription not receiving updates after mutation despite correct resolver configuration
I'm testing a new approach and Quick question that's been bugging me - I keep running into I'm using AWS AppSync to implement a GraphQL API, and I've set up a subscription for real-time updates. However, after performing a mutation, the subscription does not receive any updates. I've set up my schema as follows: ```graphql type Message { id: ID! content: String! } type Mutation { createMessage(content: String!): Message } type Subscription { onCreateMessage: Message @aws_subscribe(mutations: [createMessage]) } type Query { getMessages: [Message] } ``` I've linked the mutation and the subscription properly in the resolver. Here’s how I configured the mutation resolver for `createMessage`: ```json { "version": "2018-05-29", "operation": "PutItem", "key": { "id": "$ctx.args.input.id" }, "attributeValues": { "content": "$ctx.args.input.content" } } ``` And here’s the resolver for the subscription: ```json { "version": "2018-05-29", "operation": "Query", "query": "query getMessageById($id: ID!) { getMessage(id: $id) }", "queryParameters": { "id": "$ctx.args.id" } } ``` When I run the mutation, it successfully adds the message to the DynamoDB table, but the subscription does not get triggered. I’ve also checked that the IAM roles have the correct permissions set, allowing both the mutation and subscription operations. I tried adding logging to my resolvers but didn’t see any relevant outputs in CloudWatch that could indicate what’s going wrong. The version of AWS Amplify I'm using is 4.3.0, and I've confirmed that the GraphQL API is properly set up in the AWS console. Can anyone provide insight into why my subscription isn't receiving updates after the mutation? I'm working on a web app that needs to handle this. Any advice would be much appreciated.
