To invoke the lambda function using AWS CLI write the following code which works fine: I am sending payload to this function with instance ID and user name as I needed this in lambda if you wan't to send anything other you can send other details as input in payload section.
#!/bin/bash
user=$(whoami)
echo Please Enter the InstanceId
read InstanceId
aws lambda invoke --invocation-type RequestResponse --function-name wu_core_auto_start_stop_lambdainvoke --region us-east-1 --log-type Tail --payload '{"bashuser":"'"${user}"'", "InstanceId":"'"${InstanceId}"'"}' outputfile.txt

Since Your bash variable is inside single quotes it won't get populated.
Test:
$ echo "${user}"
root
Your sample:
$ echo '{"bashuser":"${user}", "InstanceId":"'i-0c4869ec747845b99'"}'
{"bashuser":"${user}", "InstanceId":"i-0c4869ec747845b99"}
You need to interrupt quoting like this:
$ echo '{"bashuser":"'"${user}"'", "InstanceId":"'i-0c4869ec747845b99'"}'
{"bashuser":"root", "InstanceId":"i-0c4869ec747845b99"}

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

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
