How to add triggers on aws lambda alias

Question

Hi all,

I am facing issue while adding triggers to the lambda function alias using command line. could you please help to resolve this issue.
s3_trigger.json file below.
{
    "LambdaFunctionConfigurations": [
        {
            "LambdaFunctionArn": "arn:aws:lambda:us-east-1:Account_id:function:my_lambda:my_lambda_alias",
            "Events": [
                "s3:ObjectCreated:*"
            ],
            "Filter": {
                "Key": {
                    "FilterRules": [
                        {
                            "Name": "Prefix",
                            "Value": "incoming-file/"
                        },
                        {
                            "Name": "Suffix",
                            "Value": ".json"
                        }
                    ]
                }
            }
        }
    ]
}

aws s3api put-bucket-notification-configuration \
    --bucket "$env-$clientname-raw" \
    --notification-configuration file://s3_trigger.json

An error occurred (InvalidArgument) when calling the PutBucketNotificationConfiguration operation: Unable to validate the following destination configurations.
