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:
Could you guys guide me to succeed in this execution?
thanks
It looks like you need to provide an outfile. So re-run it as follows:
aws lambda invoke \
--function-name arn:aws:lambda:us-east-1:111111111:function:xxx \
--invocation-type RequestResponse \
outfile.txt
runtime.ImportModuleError cannot find module 'app' when I tried to test my lambda locally - this is probably due to my old windows 8 and docker toolboxIn addition to @jarmod's answer:
You can use - if want to send output directly to stdout:
aws lambda invoke --function-name my_function --invocation-type RequestResponse --log-type Tail - | grep "LogResult"| awk -F'"' '{print $4}' | base64 --decode
or if you have jq
aws lambda invoke --function-name my_function --invocation-type RequestResponse --log-type Tail - | jq '.LogResult' -r | base64 --decode
-. The content of the file are{}. I have to manually delete it each time I run the macro. Specifically, my line of code is this AWS_PAGER="" aws lambda invoke --function-name paypal_ipn --invocation-type RequestResponse --payload fileb://"$tmp_dir"/invoke-payload.json --log-type Tail - | grep "LogResult"| awk -F'"' '{print $4}' | base64 --decodeoutputfile.txt (like in @jarmod 's answer), or otherwise print out the output of the function using your code.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
