I am trying to get list of ListTranscriptionJobs or StartTranscriptionJob using Amazon.TranscribeService but getting exception Authentication failed because the remote party has closed the transport stream.
At the same time from same PC and using same key I am able to access above methods from amazon cli and python code.
1) Do I create 3 s3 buckets DEV, QA and PROD where I will publish these functions?
2) I am planning to input environment name like DEV, QA and PROD to SAM template to create all lambda functions and DynamoDB with name starting as DEV,QA or PROD. That way, I don't need to use Lambda versions and aliases. Is this a good strategy? Is there any simpler, better strategy?
3)I believe only my Lambda function handler would be going to DEV, QA and PROD environment? Since I will have single SAM and CloudFormation template, how should I manage this template in a Code Source repository like Git?
Hi, I submitted a pull request about adding a ServiceCollection extension method for supporting TryAddAWSService (aws/aws-sdk-net#935) Could I get some feedback on it?
If it's something that you don't want in the library for one reason or another, or maybe I could see the functionality merged in in the future?
It would be very useful to have this functionality for me personally, so would be good to know if I could potentially get it from the SDK or should I just implement it in my own apps.
Hello. I have an issue with refreshing tokens on Cognito User Pool. I use the example from documentation to log - in. After a successful login (SessionTokens of user object is filled) I try to refresh the token using :
user.StartWithRefreshTokenAuthAsync(new InitiateRefreshTokenAuthRequest()
{
AuthFlowType = AuthFlowType.REFRESH_TOKEN_AUTH,
});Unfortunately the call results in Invalid RefreshToken exception. This is in my test application, In which i do it immedietly after login, in a production app I will be refreshing the token only if needed.
Am I doin sth wrong here, or this is a bug ?
Any tips on how to make lambda handler c# code more efficient from .NET perspective?
Some of the example questions I am trying to address:
1) WIll making lambda functions static increase reuse of Lambda context and improve performance?
2) If I make Functions class ( which has all lambda handlers) singleton class, will it improve performance?
3) If I make constant/readonly variables and share it across lambda functions, will it improve performance?
If anyone has any information, please suggest
1) I don't think that static variables are good way to keep any information. Container of Lambda function could be restarted and you lose your data. AFAIK it must be restarted each 4 hours. Google "cold start" for more information.
Try to use key-value storage (like Redis) to persist shared information. But in this case it will not be REST architecture (REST should not keep a client state on the server, be stateless).
2) It doesn't look as good idea also. At least, you will have to think about locking and state sharing between calls in this case. Make a test and write your results. It is interesting.
3) I guess - no. Changes will be unseen and doesn't worth efforts. But I am doing like for simplifying development process.
Hi guys, I'm new to AWS and I've been trying to fix an issue I have with the appsettings.json... been looking for a fix for 3days now ..
I just wanted to know if there is a way to specify which Appsettings to use when deploying a .Net Core application? I have (Dev, Staging and Production) I'm using the Publish to Elastic Beanstalk in my Visual Studio 2017.
It seems during multiple login user, it tries to access previous user identity data that was cached. So I think I need to clear credentials
I have found 3 methods of CognitoAWSCredentials to clear cache:
Clear,
ClearCredentials()
ClearIdentityCache().
Only Clear seems to work. However I have read documents and it mentions that we should use ClearCredentials or ClearIdentityCache.
I am developing an app with UNITY 2017.2.3f1 and the aws-sdk-unity_3.3.396.2
S3 works fine which means that many elements are OK. The code works fine for MAC and Android
However when I try to post an element on DynamoDB with the following code
var rec = new Document();
rec["id"] = 1;//recName;
rec["Lat"] = 2;//Input.location.lastData.latitude;
rec["Long"] = 3;//Input.location.lastData.longitude;
rec["Time"] = 4;//recTime;
table.PutItemAsync(rec, (r) => {
Debug.Log("\n rec has been poted " + r.Exception + " *222444*****************");
textnotification.text = "Archivo subido con éxito";
Invoke("cleanText", 3);
butSender.interactable = false;
butPlayer.interactable = true;
butRecorder.interactable = true;
hasnotbeensent = false;
});it complains with the following error.

I think it is a Bug but I am not sure.
