• Upload file from html when block public access is true

  I am using django-s3direct to file upload

  https://github.com/bradleyg/django-s3direct

  Using IAM role setting because I upload the file from the server on ECS container.

  Now I set the blockPublicAccess of S3 false.

  When uploading images from html, there comes error.

  https://s3.ap-northeast-1.amazonaws.com/static-resource-v/images/c64d6e593de44aa5b10dcf1766582547/_origin.jpg?uploads (403 (Forbidden)

  OK, it is understandable.

  Browser try to access the for initiation.

  However there is any way to upload file from browser when blockPublicAccess is true??

• AWS Pinpoint sendMessages() Addresses param field error

  I'm having trouble replicating the format of the params object's Addresses format in a way where I can easily add to the object.

  If I use this as the params with destinationNumber[0] and destinationNumber[1] in the format of 1 + 9 digit number ie 13334535667 then it sends the message to both numbers no problem.

   const params = {
          ApplicationId: applicationId,
          MessageRequest: {
              Addresses: {
                  [destinationNumber[0]]: {
                      ChannelType: 'SMS'
                  },
                  [destinationNumber[1]]: {
                      ChannelType: 'SMS'
                  }
              },
              MessageConfiguration: {
                  SMSMessage: {
                      Body: message,
                      Keyword: registeredKeyword,
                      MessageType: messageType,
                      OriginationNumber: originationNumber
                  }
              }
          }
      };
  

  I'm trying to replicate this format for Addresses, but I'm getting Unexpected key '13334535667' found in params.MessageRequest.Addresses['0']. The format my console output shows for Addresses is

  [
    { '12345678910': { ChannelType: 'SMS' } },
    { '12345678911': { ChannelType: 'SMS' } }
  ]
  

  I'm using a map to call this

  function createPhoneMessagingObject(phoneNumber: string) {
      return {
          [phoneNumber]: {
              ChannelType: 'SMS'
          }
      };
  }
  

  I tried wrapping key in array like in phone object, but per the output, the brackets goes away so maybe there's an easier/more correct way of doing this. I appreciate any help!
• AWS Lambda Function Direct Post Payload Always Null

  I'm trying to use Lambda Functions (C#) with the Function URL for direct access. In postman I'm sending a basic json body that matches the class properties in my input parameter (PostBody). When I execute the POST request, the values are always null tho. Is the input supposed to be something else besides the expected class?

• Is there a way to filter with AWS SNS filter policies from the message body to SQS queues?

  I have a general question about SNS filter policies. I know that the filter policies filter based on the Message Attributes. If we wanted to filter based on the body, is there a work around to do so?

  The SNS topic will be delivering different types of data to SQS queues based on the filter policies.

• How to pass a parameter to a Spring Cloud Function?

  I'm following the Spring Cloud Function tutorial.

  In the example, they are calling the revert bean with this command:

  curl localhost:8080/reverseString -H "Content-Type: text/plain" -d "abc"
  

  I like to call the endpoint from a browser/postman as a GET request.

  So I was looking to orchestrate a URL with a query parameter, that may look like localhost:8080/reverseString?input=abc

  But:

  1. It is not clear to me what should be the name of the parameter?
  2. Seems like no matter what method name we put, they all get HTTP 200 response, with no response body. reverseStringggg, reve ...
• How to get Context for logging when using APIGatewayProxyRequestEvent in aws-lambda

  My project is written in spring-cloud-function and deployed in aws-lambda. I have a requirement wherein I am supposed to log the events.

  A little search told me to use

  com.amazonaws.services.lambda.runtime.Context for logging by doing this:

  context.getLogger().log("log event here");
  

  I have a spring cloud function which receives APIGatewayProxyRequestEvent as the input and APIGatewayProxyResponseEvent as the output parameter

  I searched again and found to get the context, this can be wrapped with org.springframework.messaging.Message

  so I wrote the function like this:

  public Function<Message<APIGatewayProxyRequestEvent>, APIGatewayProxyResponseEvent> saveEmployee(){
  return request -> {
              Context context = request.getHeaders().get("aws-context", Context.class);
  context.getLogger().log("employee save request---: " + request);
      //do something
  

  However the context evaluates to null and I get NullPointerException

  Can someone point to what might be going wrong? or how to fetch context?

  Thanks in advance
• POST search api execution throwing Execution failed due to configuration error: Status code must be between 100 and 599

  I have spring-cloud-function project deployed in aws-lambda hit by api-gateway.

  I have a search api implemented using POST method with the following request body

  {
    "criteria": {
      "name": "employeeId",
      "value": 22
    }
  }
  

  The name of the function has been configured in aws-lambda environment variable configuation using the key as: spring_cloud_function_definition and value as getEmployeeById

  Also the handler has been configured with the following value: org.springframework.cloud.function.adapter.aws.FunctionInvoker

  For testing purposes I have kept the code of my function to be very simple for now. I actually removed a lot of code due to the same exception as I am going to share below. So now the code looks something like this:

  @Bean
      public Function<Message<APIGatewayProxyRequestEvent>, APIGatewayProxyResponseEvent> getEmployeeById(){
          
          return request -> {
              try {
                  
                  APIGatewayProxyResponseEvent responseEvent = new APIGatewayProxyResponseEvent();
                  responseEvent.setBody("test employee");
                  return responseEvent;
                  
              }
              catch(Exception e) {
                  
                  e.printStackTrace();
                  e.getMessage();
                  throw new RuntimeException(e.getMessage());
              }
              
          };
          
      }
  

  However when I hit the api-gateway(configured to call the lambda) with the request body as shown above, I get the following exception:

  Endpoint response body before transformations: {"statusCode":null,"headers":null,"multiValueHeaders":null,"body":"test employee","isBase64Encoded":null} Thu Apr 28 10:15:51 UTC 2022 : Execution failed due to configuration error: Status code must be between 100 and 599 Thu Apr 28 10:15:51 UTC 2022 : Method completed with status: 502

  Looks like some configuration issue. Any suggestions as to what might be going wrong?

  Thanks in advance
