问题 This question already has answers here : TypeError: string argument without an encoding (3 answers) Closed yesterday . I'm trying to save password string encrypted in DynamoDb, I get this error. Response: { "errorMessage": "string argument without an encoding", "errorType": "TypeError", "stackTrace": [ " File \"/var/task/lambda_function.py\", line 25, in lambda_handler\n encrypted_password = encrypt(session, plain_text_password, key_alias)\n", " File \"/var/task/lambda_function.py\", line 11,

问题 I'm trying to figure out how to automatically kick off an AWS Glue Job when an AWS Glue Crawler completes. I see that the Crawlers send events when they complete, but I'm struggling to parse through the documentation to figure out how to listen to that event and then launch the AWS Glue Job. This seems like a fairly simple question, but I haven't been able to find any leads so far. I'd appreciate some help. Thanks in advance! 回答1: You can create a CloudWatch event, choose Glue Crawler state

问题 I am doing a lab on the website LinuxAcademy.com. The Course name is Automating AWS with Lambda, Python, and Boto3 and the specific lab I am having trouble with is Lecture: Importing CSV Files into DynamoDB . In this lab we upload a .csv file into S3, an S3 event is generated in a specified bucket which then kicks off the Lambda function shown below. The function parses the .csv then uploads the contents into DynamoDB. I was originally having issues with Line 23: items = read_csv(download

问题 predict = [0.1,0.2] payload = { "instances": [ { "features": predict } ] } response = linear_regressor.predict(json.dumps(payload)) predictions = json.loads(response) print(json.dumps(predictions, indent=2)) The above code is able to invoke the endpoint which is the linear-learner endpoint and give the below result. { "predictions": [ { "score": 0.13421717286109924 } ] } But when I try to invoke the endpoint using below lambda function, import json import io import boto3 client = boto3.client

问题 I have a Lambda function that imports a node package with common functions. Lambda 1 puts messages into SQS, Lambda 2 does error logging. One of the shared functions invokes Lambda 2, but there's an error on that second invocation. Lambda 1: exports.handler = function (event, context) { var pnmacCommon = require('./pnmacCommon.js'); //loading node package try { // this part omitted for space var aws = require('aws-sdk'); var sqs = new aws.SQS({ region : 'us-west-2' }); var params = {

问题 I have the following Promise.all example. I was wondering if it was operating in "parallel" in regards to the lambda.invoke ? And how can I test if something is running parallel? Referenced this thread function get1(id) { return new Promise((resolve, reject) => { const params = { FunctionName: 'myLambda', // the lambda function we are going to invoke InvocationType: 'RequestResponse', Payload: { id }, }; lambda.invoke(params, (err, data) => { if (err) { reject(new Error('error')); } else {

问题 I'd like to run some code using Lambda on the event that I create a new EC2 instance. Looking the blueprint config-rule-change-triggered I have the ability to run code depending on various configuration changes, but not when one is created. Is there a way to do what I want? Or have I misunderstood the use case of Lambda? 回答1: You could do this by inserting code into your EC2 instance launch userdata and have that code explicitly invoke a Lambda function, but that's not the best way to do it.

问题 We're developing an AWS Lambda function for Alexa skill in Python and using pip to install the ask-sdk package to our dist/ directory: pip install -t dist/ ask-sdk The trouble is with the -t dist/ because pip wants to have all the dependencies there, even if they are installed system-wide. Now, ask-sdk has a dependency on boto3 which pulls in a whole lot of other packages. However the AWS Lambda runtime environment provides boto3 and there is no need to package that and its dependencies with
