"I get a "410 GoneException" error when trying to post a message to my Amazon API Gateway WebSocket API similar to the following:..."errorMessage": "GoneException: 410"...How do I troubleshoot this?Short descriptionYou might receive the "410 GoneException" error if:A message was posted to the WebSocket API before the connection was established.The connection has been terminated, or the connection doesn't exist anymore.The client disconnected and then tried to reconnect using the same connectionId.Note: For WebSocket APIs, the connectionId is required to send a callback response from the backend.ResolutionTo troubleshoot WebSocket API errors, turn on Amazon CloudWatch Logs.Note: For Log level, choose INFO to generate execution logs for all requests.Execution logs contain information that you can use to identify and troubleshoot most API errors. For example:The requests that your API receivesThe integration backend responses from your APIThe response provided by AWS Lambda authorizersThe requestId for AWS integration endpointsFor more information about each type of logging, see CloudWatch log formats for API Gateway.Before posting messages to WebSocket APIs, make sure that your connection is established by calling the getConnection operation using the AWS SDK ApiGatewayManagementApi.Avoid making the postToConnection request from the Lambda function integrated with your $connect route. For example, if you want to post a message after the client connection is established, do the following:Create a child Lambda function that's asynchronously invoked by the parent function.On initiation of a new connection, the $connect route is invoked and the parent function invokes the child function passing the connectionId.The Lambda child function receives the connectionId and calls the getConnection operation to verify that the connection is valid. Then, the message is sent using the postToConnection method.Related informationAbout WebSocket APIs in API GatewayHow can I pass a connectionId or custom token to VPC Link integration as a header for Amazon API Gateway WebSocket APIs?Follow"
