Hi team, I'm trying to update my CDK version from V1 to V2 in my packege.json, I changed the version from "^1.153.1" to "^2.25.0" but I have compilation errors when doing npm install ... for example ``` npm ERR! code ETARGET npm ERR! notarget No matching version found for @aws-cdk/aws-apigatewayv2-authorizers@^2.25.0. npm ERR! notarget In most cases you or one of your dependencies are requesting npm ERR! notarget a package version that doesn't exist. ``` how can I keep my existing code for my CDK stacks working with the V2 version or should I rewrite the CDK code? Thank you :)

We've tested with ec2 and Cloud9 and I connected to Studio 3t using ec2 ssh tunnel. And I follow the example of programming connection https://docs.aws.amazon.com/documentdb/latest/developerguide/connect_programmatically.html There is a timeout error locally in NodeJS, so I am asking. Even if you try to access using .pem file locally in NodeJS, a timeout error occurs and asks. What is the reason and how can I improve it? I'm sharing the source below. Thank you in advance ``` var MongoClient = require('mongodb').MongoClient; var username = 'DBusername'; var password = 'DBpassword'; var client = MongoClient.connect( `mongodb://<DBusername>:<DBpassword>@<clusterendpoint>:27017/<DBname>?tls=true&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false`, { tlsCAFile: `./rds-combined-ca-bundle.pem`, }, function (err, client) { if (err) throw err; //Specify the database to be used db = client.db('DBname'); //Specify the collection to be used col = db.collection('CollectionName'); //Insert a single document col.insertOne({ hello: 'Amazon DocumentDB' }, function (err, result) { //Find the document that was previously written col.findOne({ hello: 'DocDB;' }, function (err, result) { //Print the result to the screen console.log(result); //Close the connection client.close(); }); }); } ); ```

Need to switch account from ADS employee to AWS employee and NOT have to pay/put in credit card. Can someone help?

I'm hosting a static website via S3 buckets and CloudFront. I've set it up so that the data is stored in the www bucket and the other, non-www, bucket routes to it. Typing in the ULR with the www works perfectly. The issue I'm running into is that when I type in the URL without the www, it routes to another site with a different, but similar URL. It's been like this for about a week and nothing I do seems to change it. I've redone the hosting zones and checked multiple times and none of it seems to work. I've done something like this before with other sites I've set up so I know what I'm doing works. I'm last as to how to go about fixing this so any help would be very much appreciated.

I recently registered a .co.uk domain thinking it could be hosted on Route 53. I later learned Route 53 isn't compatible with the storefront service that the domain was intended to point to. Cloudflare is compatible and I've moved NS authority to their platform and updated NS in Route 53. However, .co.uk domains are managed by Gandi and I also need to update NS records there. Simply updating on Route 53 didn't update Gandi. I don't have a Gandi account, how do I make these changes?

- I'm using Quectel modem BG95 with a host MCU to connect to AWS IoT core and publish to topics and subscribe to topics as well. - I used to get an error occasionally that closed the MQTT connection exactly while doing pub/sub operations and connection had to be re-established , but that was very rare. - However, since the last few days I have been running tests on multiple devices (using same IoT core endpoint) and have been getting this MQTT dis-connection on each pub or sub operation. I am attaching a log for review. - To me it seems a server side issue since I have tried it with multiple modems and previous versions of firmware. ``` [While publishing to topic] ;2022-05-08T02:29:41Z;28;-966233403;462863960;;RAK000121|-45,RAKTEST|-56 AT+QIDEACT=1 OK[ 2022-05-08T02:29:41Z ] [FARM_IP][INFO] MDM_SET_DEACTIVATE_PDP-else AT+QIACT=1 OK AT+QMTOPEN=0,"a5u9klmd2viw3z-ats.iot.us-west-1.amazonaws.com",8883 OK +QMTOPEN: 0,0 --- [Opening MQTT Connection] [ 2022-05-08T02:29:41Z ] [FARM_IP][INFO] Mqtt opened AT+QMTCONN=0,"0123qwer786" OK +QMTCONN: 0,0,0 --- [MQTT client connected] AT+QMTPUB=0,1,1,0,"fm/1011",72 --- [Publishing to the MQTT Topic] > ;2022-05-08T02:29:41Z;28;-966233403;462863960;;RAK000121|-45,RAKTEST|-56 OK +QMTSTAT: 0,1 --- [MQTT Connection Closed] ``` ``` [While Subscribing to topic] AT+QMTSUB=0,1,"imei/get_logs",0 --- [Subscribing to the MQTT Topic] OK +QMTSTAT: 0,1 --- [MQTT Connection Closed] [ ] [FARM_IP][INFO] Starting timer AT+QMTSUB=0,1,"imei/get_logs",0 --- [Subscribing to the MQTT Topic] OK +QMTSTAT: 0,1 --- [MQTT Connection Closed] ```

Hello, CX have below workflow and would like to know if we can increase the time out. ~~ VirtualGateway -> GatewayRoute -> Virtual Service->Virtual Node ~~ By default the timeout value is 15 sec in Virtual Node configuration according to this AWS doc[1]. Also I tried increasing this value in Virtual node listener but still have issues, Also, at the moment the only concern is where can we set timeouts in Appmesh other than virtual node configuration as per the above workflow? To be able to set a timeout greater than the default value we would need to setup a virtual router and a route with a timeout greater than the default. I tried according to this doc[2] but still receiving timeout error's at 15 sec. Links: [1]https://docs.aws.amazon.com/app-mesh/latest/userguide/virtual_nodes.html [2]https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-appmesh-route-httptimeout.html

Hi team, I'm looking for the best option to handle SES feedback loop in AWS? We have to handle bounces and complaints. if the user REPORT SPAM or if the email bounces (because you delete your email or the mailbox is full). **so we need to store feedback loop somewhere ** Thank you :)

Hi, We want to implement a pessimistic locking of code commit and wanted to find out steps to implement this. Would appreciate if anyone can provide guidance on this. Thank you

Hello, I have created a Lambda function that fetched the static/hash token from the environment variables in the Configuration section. When I try to export the Lambda function using the Action > Export function, a zip file is downloaded without any configuration-related data in it. Is there a way to export the environment variables from the Lambda functions?

One box stage in CICD pipeline is a stage before production stage. This stage also will receive the production traffic. The goal of this stage is to validate the new changes with very small prod traffic and keep the blast radius to minimal incase of issues. In server based deployment, this stage will contain only 1 machine to receive very small % of traffic. The code changes will be deployed to 1-box stage before production and leave it for some time to validate the behaviour of new change. If there is an issue in 1-box stage with the new code, the blast radius will be minimal and roll back is faster since the changes are deployed in only one machine. It is explained in "Backward compatibility and one-box testing" topic in this link - https://aws.amazon.com/builders-library/automating-safe-hands-off-deployments/ How do we setup the same in lambda ci-cd ? Any leads on this will be super helpful.

I have a few lambdas written in C#. There are some functions which can be reused among these lambdas. How can I achieve that?

How can I check the cost of network load balancer with cross-zone load balancing enabled on AWS console? Cross zone load balancing only.

In server setup, the connections to RDS DB (Aurora) instances has pool where the connections are bit long lived and cached. This will give us faster connectivity. I would like to understand the guidance on this scenario for serverless/lambda. With lambda there is no sessions and no connections are cached. I think it will create connections every time, it might impact the performance. Are there any workaround or solves/guidance for Lambda ? Is it okay to open the connection every time with the DB instances ? Any leads on this will be super helpful ?

Can we make the lambda function urls not accessible from public internet and accessible only with in the vpc ? I do understand using AWS_IAM we can reject the requests from malicious users. I am wondering about the ways to restrict the access within VPC, zero access from public internet.

I want to host a python code based service in Lambda behind API GW. AFAIK, there are 2 approaches to deploy the code to Lambda. 1. simply zip the code and upload to S3 and link with the lambda function 2. create ECR images and deploy it with lambda function. Are there any guidance on when to use ECR ? and when to use simple code zipping ? What are the pros and cons of each approach ? Some leads on this topic will be super helpful.
