Subscription connection failed #5
Description
I'm following the workshop in YouTube, and after adding GraphQL subscription I'm getting the following error:
WebSocket connection to 'ws://192.168.100.18:20002/graphql?header=eyJob3N0IjoiMTkyLjE2OC4xMDAuMTg6MjAwMDIiLCJ4LWFtei1kYXRlIjoiMjAyMDA0MTlUMTgxNjMzWiIsIngtYXBpLWtleSI6ImRhMi1mYWtlQXBpSWQxMjM0NTYifQ==&payload=e30=' failed: Error during WebSocket handshake: Unexpected response code: 404
And the following object error (stringified):
{

"aws_appsync_graphqlEndpoint": "http://192.168.100.18:20002/graphql",

},

"subscriptionObserverMap": {},
"promiseArray": [],
"awsRealTimeSocket": null
},
"error": {
"errors": [
{
"message": "Connection failed: Connection handshake error"
}
]
}
}Error is being thrown from
projectFolder/node_modules/zen-observable-ts/node_modules/zen-observable/lib/Observable.js
I've been updating the code while following the workshop in this repo.
EDIT:
I changed the logger used in the amplify module to be verbose, if it helps, this is what is printed out in the browser console:
