AWS CLI execute a lambda function issue

Question

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

In 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

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
