I'm trying to invoke a lambda function from my AWS CLI in windows 10. I've done previously a configuration of my client thru AWS configure.

The command used is:

aws lambda invoke \
    --function-name arn:aws:lambda:us-east-1:111111111:function:xxx \
    --invocation-type RequestResponse

but my system is returning an error aws: error: too few arguments, as shown below:

enter image description here

Could you guys guide me to succeed in this execution?

thanks

In case you are integrating with Jenkins(Windows) and dont want to use Lambda plugin. Lambda plugin is somehow not taking credentials I set in jenkins binding.

Prepare payload first. I have taken parameters from user.

@echo off
@echo {> payload.json
@echo  "type": "RequestType",>> payload.json
@echo  "siteCode": "%SiteCode%",>> payload.json
@echo  "siteDesc": "%SiteDesc%",>> payload.json
@echo }>> payload.json

Invoke lambda using aws cli.

aws lambda invoke --function-name "FuntionName" --invocation-type RequestResponse --region us-zone-id --log-type Tail --payload file://payload.json response.json

You can print response using type command.

type response.json

AWS CLI version details

aws-cli/2.1.13 Python/3.7.9 Windows/10 exe/AMD64 prompt/off

Invoke Lambda cmd, Payload needs to be Base64 encoded (https://www.base64decode.org/), you can also install plugin if needed

aws configure // If applicable perform the aws configure
aws lambda invoke --function-name test_details:DEV  --payload #yHw response_test.json

success response

{
    "StatusCode": 200,
    "ExecutedVersion": "18"
}

The response_test.json should be generated under same path. Ref document https://awscli.amazonaws.com/v2/documentation/api/latest/reference/lambda/invoke.html
