This is a great video! Thank you so much! I tried to follow the exact steps, but I kept get "Object reference not set to an instance of an object", do you have nay idea?
@@andiyan5268 Glad you like it - what line does it throw that error? Any screenshot or logs that you can share. Cloudwatch logs might have more info if you haven’t looked already
Thank you for the video. What if we use a clean architect or large application, is this the best way to do it? Or can we create a lambda function for each API controller level? As per my understanding, Lambda should be light. if we deploy a complete solution as a single lambda fiction it will cause performance issues.
Anyone can help me with this error after this command {Enter Runtime: (The runtime environment for the Lambda function) dotnet8} : error : The NuGetSdkResolver did not resolve this SDK because there was no version specified in the project or global.json.
You sir have earned a subscriber!!! Is there any possibility you could show how to add functionality within the REST API for something like a shopping cart application in the future?
Thank you so much for sharing. Can you please show how to create Function URL for any REST web api in the same project as you are showing in the video. Thanks!
Hey Ajay Glad you like the video. I do have two other videos on Function URLs in this series bit.ly/aws-net-series Did you get a chance to see those? What trouble are you running into?
@@RahulNath thank you for your reply. I watched your other video of URL and I followed the same steps and and made auth to NONE, even then my Function URL is returning 'Internal server error' where as if I am using the URL which I got in the Visual Studio after deployment is working perfectly fine, not sure where I am missing some thing. Thanks.
You are missing some important steps I guess. First I get Error retrieving configuration for function apixxxxxx Unable to get IAM security credentials from EC2 and second I dont get Publish to AWS even after the Lambda is added.
Hey Julian, How are you running the application? In the demo I am running it on my local machine and not an EC2 instance. Not sure why you are getting the IAM security error related to EC2. Also do you have the AWS Toolkit setup and the local credentials set up? I talk about this here www.rahulpnath.com/blog/amazon-credentials-dotnet/
what's the difference between connecting the lambda to api gateway to no connection? when it works without the api gateway that you introduced in the later part of the video?
API Gateway provides more out of the box capabilities when building APIs. So if you want to use that while exposing on Lambda you can choose that option. There is a video on API Gateway in this series here bit.ly/aws-net-series. Let me know if that helps.
Isn't the idea of lambda functions to keep the functions tiny where endpoints are split up into separate lambda functions? From what I understand of this video this lambda function is actually a monolithic application.
It always doesn't have to be separate endpoints. You can have a domain aggregarte API in a single endpoint. Also boils down to how you want to scale the functions etc as well. I wouldn't recomment having the entire application on it - but yes that is also a possibliity and comes down to the use case. Hope that helps.
Looks like a permission issue Nishant. For whatever action you are trying to do on the AWS resource you need that permission. Not sure what exactly the code is doing in your case.
Thanks for the content. I have an aspnet 6 webapi with many CRUDs, if I use lambda to host it, could I get error if call an endpoint that takes 2 minutes to do something (in a db transaction) but my lambda is ending, i.e, 15 minutes is the max time, after that he dies and my suppose transaction dies to. If I call my endpoint first time, the lambda will lives for 15 minutes (max that I cofigured) or it will die and for each calls it will starting again?
Not sure if I fully understand the question, but maybing check out this post/video on Lambda Lifecycle might help you understand this better www.rahulpnath.com/blog/lambda-lifecycle-and-net/ If not can you explain your scenario in more details.
you are doing awesome work to help IT community, by making such a amainzing content
thanks you so much!
Thank you Raj! Glad you are liking the videos.
If I found this video a year before, I can save lot of time. I host a webapi project in lambda a year ago..
Yeah I am late with this guess 😂
Thank you very much, you are good at explaining!
You are welcome! Hope you are enjoying the AWS Series bit.ly/aws-net-series
Great Content as allways! Thank you.
Glad you enjoyed it Knulp!
Excellent, Thanks friend
Awesome tutorial sr. Thank you so much

Glad you like the content. Can you provide more details on what you are looking to achieve. Hopefully I will do a video on that
Very cool!
Thank you Antonio! 😀
the best!

Muy bueno
Thank you hector!
I am Getting this Error please help!
In particular it says IAM is not authorized to perform iam:ListRoles nor iam:ListPolicies.

Hi can you tell me how I can check implementation of inbuilt method is there any extensions available in visual studio?
I have Resharper which helps with that. Not sure if there is a way out of the box with VS. Or I use Rider which also does a good job with it.
@@RahulNath thank you..
so we don't need to buy any hosting for webspi. is there any limitations to host on lamda?
very good vid, thnx, but what about the database ? how can we host and connect it ?
What database are you using? I would either use a cloud hosted on like DynamoDB, SQL on RDS etc or self host it. What are you trying to achieve?
