ENOUTFOUND API Gateway websocket.

[Y2KForever]

Hi, I'm trying to send a message to all the clients that's connected to an API Gateway websocket, but I keep getting the error

Error: getaddrinfo ENOTFOUND execute-api.eu-central-1.amazonaws.com
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:69:26) {
  errno: -3007,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'execute-api.eu-central-1.amazonaws.com',
  '$metadata': { attempts: 1, totalRetryDelay: 0 }
}

Which is really odd, since the everything is hosted on EU-central-1.

The code I have is this:

const {
  ApiGatewayManagementApiClient,
  PostToConnectionCommand,
} = require("@aws-sdk/client-apigatewaymanagementapi");

exports.sendEvent = async (event) => {
  const apiGatewayMng = new ApiGatewayManagementApiClient({
    apiVersion: "2018-11-29",
  });
  try {
  /* ConnectionData is collected earlier, I've checked that connection id is correct and existing  */
      for (const conn of connectionData.Items) {
        );
        const params = {
          ConnectionId: conn.connection_id.S.toString(),
          Data: "test",
        };
        await apiGatewayMng.send(new PostToConnectionCommand(params));
      }
    }
  } catch (e) {
    console.log(e);
    return {
      statusCode: 500,
      body: JSON.stringify(e),
    };
  }
  return {
    statusCode: 200,
    body: "update sent successfully.",
  };
};

Anybody got an idea why it's not working?

You need to specify the endpoint specifically in the configuration of ApiGatewayManagementApiClient.

It will typically take a form like "https://{api-id}.execute-api.{region}.amazonaws.com/{stage}" and you can find in the API Gateway page in the AWS console.
