Issue while invoking lambda on localstack
Hi,
I am facing an issue when I am trying to invoke a node js lambda function from CLI.
Below are the steps which I have followed to create and invoke lambda function.
Step 1: I created node js function helloworld.js. Below is it's code snippet.
console.log('Loading function'); exports.handler = function(event, context, callback) { console.log('value1 =', event.key1); console.log('value2 =', event.key2); console.log('value3 =', event.key3); callback(null,"Success");
};
Step 2: Zipped this file as helloworld.zip
Step 3: Create lambda function using the below-mentioned command.
Command: aws --endpoint-url=http://localhost:4574 lambda create-function --region us-east-1 --function-name helloworld --zip-file fileb://helloworld.zip --role arn:aws:iam::000000000000:role/lambda_basic_execution --handler helloworld.handler --runtime nodejs6.10 --profile default --description "SNS X Account Test Function" --timeout 60 --memory-size 128 --environment Variables={LAMBDA_EXECUTOR=docker}
Below is the output of list-function command aws --endpoint-url=http://localhost:4574 lambda list-functions { "Functions": [ { "Version": "$LATEST", "FunctionName": "helloworld", "FunctionArn": "arn:aws:lambda:us-east-1:000000000000:function:helloworld", "Handler": "helloworld.handler", "Timeout": 60, "Runtime": "nodejs6.10" } ] }
Step 4: Tring to invoke lambda function
Content of file://input.txt { "key1": "value1", "key2": "value2", "key3": "value3" }
Command: aws --endpoint-url=http://localhost:4574 lambda invoke --invocation-type RequestResponse --function-name helloworld --region us-east-1 --log-type Tail --payload file://input.txt --profile default outputfile.txt
