错误 Lambda 函数处理程序

Question

this is my lambda function-

import boto3

def send_function(event, context):

    valu=event['VAL']
    mname=event['MNAM']
    d=boto3.client('cloudwatch')
    d.put_metric_data(Namespace='WebStatus',
        MetricData=[
            {
            'MetricName': mname,
            'Dimensions': [
                {
                'Name': 'Status',
                'Value': 'WebsiteStatusCode'
                },
            ],
            'Value': valu,
            },
        ]
    )

and i get error - "errorMessage": "Unable to import module 'lambda_function'"

Answer 1

This error happens when you define wrong lambda handler name while you upload your lambda function. The name of the lambda handler has to be <your python filename>.<your method name> .

So if your python filename is hello_python.py , the lambda handler should be defined hello_python.send_function . For more info, read this .
