• C# - Adding condition to func results in stack overflow exception

  I have a func as part of specification class which sorts the given iqueryable

  Func<IQueryable<T>, IOrderedQueryable<T>>? Sort { get; set; }
  

  When i add more than one condition to the func like below , it results in stack overflow exception.

  spec.OrderBy(sc => sc.Case.EndTime).OrderBy(sc => sc.Case.StartTime);
  

  The OrderBy method is implemented like this

  public ISpecification<T> OrderBy<TProperty>(Expression<Func<T, TProperty>> property)
      {
          _ = Sort == null ? Sort = items => items.OrderBy(property) : Sort = items => Sort(items).ThenBy(property);
          return this;
      }
  

  Chaining or using separate lines doesn't make a difference.

  This problem gets resolved if I assign a new instance of the specification and set it's func, but i don't want to be assigning to a new instance everytime. Please suggest what am i missing here and how to reuse the same instance (if possible).

  I have several URLs that I need to create a redirect rule. I need to remove "2011" from the url and change the URL... I got most of it working but I can't figure out how the "-" or "+" needs to be written and how to combine into one rule

  <rule name="Redirection 1" stopProcessing="true">
     <match url="test-catalog/([0-9]*)//abc-and-def/([0-9]*)"/>
     <action type="Redirect" url="https://someserver.com/path01/overview/{R:2}#/abc-and-def"/>

     <action type="Redirect" url="https://someserver.com/path01/overview/{R:2}#/abc-and-def"/>
  </rule> 
  

  I tried to use this use rule but it's not working !!

  <rule name="Redirection rule " stopProcessing="true">

• Windows Server 2022, IIS 10, and SSL - Website is not loading

  When my website is installed on Windows server 2016 and 2019 it works perfectly. On Windows Sever 2022 I get an error of "This site can’t be reached The connection was reset" but if I go to IIS -> SSL -> and change client certificates to Ignore instead of Accept or I can go to IIS -> bindings -> port 443 -> select disable TSL 1.3 over TCP it loads up correctly

  Can someone explain why this is happening? What Can I do? I don't want to do any of those options
• Python code stops automatically after 2-4 hours on AWS EC2

• Assign ELB Account to S3 Bucket Policy

  I used the AWS console from the load balancer edit attributes screen and used it to create a bucket to use for access logging. I'm using this policy to form CDK code in typescript to stand up new S3 buckets to use for access logging in higher level environments where I cannot use the console. This is the policy I need to somehow form in typescript CDK code:

  "Statement": [
  {
      "Effect":Allow",
      "Principal": {
          "AWS": "arn:--ELB-arnstuff--:root"
      },
      "Action": "s3:PutObject",
      "Resource": "arn:--S3-Bucket-arnstuff--/AWSLogs/123456789/*"
  }
  ]
  

  I've managed to get the cdk code figured out to this point:

  bucket.addToResourcePolicy(
      new cdk.aws_iam.PolicyStatement({ 
        effect: awsIam.Effect.ALLOW,
        principals: //'**This is part I haven't figured out**',
        actions: ['s3:PutObject'],
        resources: ['${bucket.bucketArn}/*']
      })
  );
  

  At this point I don't care if it's hard coded in the CDK, I just need something to help keep the ball rolling forward. Any help is appreciated, thanks
• AWS API Gateway: Why setting "application/json" mapping template for GET request is required for MOCK integration to work?

  I'm setting up a mock integration for GET requests with AWS API Gateway, and wonder why it only works when the application/json request template is specified. To my understanding GET request does not have a body and hence does not have a Content-Type header. What is special about 'application/json'? Is this behavior documented somewhere or am I missing some defaults somewhere?

  Here is terraform code for my API Gateway:

  resource "aws_api_gateway_rest_api" "test-api" {
    name = "test-api"
  
    endpoint_configuration {
      types = ["REGIONAL"]
    }
  
    body = jsonencode(yamldecode(file("openapi.yaml")))
  }
  
  

  openapi: "3.0.1"
  info:
    version: "1.0"
    title: example
  
  paths:
    /test:
      get:
        responses:
          "200":
            description: demo
            headers:
              Content-Type: { schema: { type: 'string' } }
  
        x-amazon-apigateway-integration:
          type: MOCK
          passthroughBehavior: when_no_templates
         
          # the next line is required. 
          # API Gateway returns 500 error if I remove it. why? 
          # API Gateway returns 415 error if I change application/json to text/plain. why? 
     
          requestTemplates: { 'application/json': '{"statusCode": 200}' }
          responses:
            default:
              statusCode: 200
              responseParameters: { 'method.response.header.Content-Type': "'text/plain'" }
              responseTemplates: {'text/plain': 'hello'}
  
  

  Here is an example log output when requestTemplates is set to{ 'text/plain': '{"statusCode": 200}' }

• Correct way to auto create aws api gateways to existing apis

  I am building 2 separate nodejs microservices (using express inside each etc).

  What is the correct way to properly automate creation of AWS Api gateway's so that they map exactly on to my nodejs apis ?
