Genius video. Really enjoyed this one. Also very well explained, 10/10 for all of it . My own further request would be that it would be nice to see and edit message feature too :)
Hey man, Nice and helpful video. Thank you. I get Forbidden error when sending message from socket client {"message": "Forbidden", "connectionId":"some_ID", "requestId":"some_ID"} I think I have not missed any step. The request does not appear in lambda logs, so I think API gateway blocks the request for some reason.
I have a question please , When a user creates a chat room and adds a members for this chatRoom ,How can we generate connectionId for each member to be able to receive connectionId
what if bob is disconnected and jimmy wants to send message to bob how to handle this situation like in chat application . The problem is connection id is recreated when ever the user is join the chat .
Very nice! But I was questioning if using Lambda what it's billed to me it's per say 100ms for each client for every message. On the other hand Lambda is taking up and storing my variables with my ids... How does Lambda bills me? Thank you!
Thank you for the video, it really helped me! I've facing an issue regarding using only serverless.yml to deploy the application. Locally everything works, but on aws the postToConnection only send if a user has joined. I'm saving the data in mongogb. Is there a huge difference by doing the firsts steps in the video and doing locally?
I really really need a urgent help if anyone can pls... Hey Alex...and other people reading this comment ...can anyone tell me how to open this CLI from lambda function whose prompt will be lambda too.... I'm.not getting how in this video at 9.30 timing the cli opens from the lambda service window.... Pls help urgent

Try to check the logs of the lambda function to see what causes the error, then troubleshoot it: aws.amazon.com/premiumsupport/knowledge-center/lambda-troubleshoot-invoke-error-502-500/

HOW lambda holds the names object ( var names = { }; ) for every request won't it become resetted ???
why should we use .promise() when we are using async and await
If anyone is trying this lately, I don't know if something changed in AWS, but I was getting bad gateway from the wscat connection. So I checked cloudwatch and it was giving me this error:
Error: Cannot find module 'aws-sdk'".
So I installed @aws-sdk/client-apigatewaymanagementapi directly and it fixed the issue.
Usage:
import {
ApiGatewayManagementApiClient,
PostToConnectionCommand,
} from '@aws-sdk/client-apigatewaymanagementapi'
const command = new PostToConnectionCommand({
ConnectionId: id,
Data: Buffer.from(JSON.stringify(body)),
})
return await client.send(command)
Can you further elaborate on this?
