This issue is with respect to another issue I had logged a few days ago [https://github.com//issues/292].

I am invoking a lambda from another lambda using python SDK. Both the lambdas belong to the same VPC. The trigger lambda only contains a python script that invokes the second lambda (loader_development) and the code for that is as under:

from __future__ import print_function

import json
import logging
import os
from urllib2 import urlopen,Request,HTTPError
import boto3
import botocore.config

logger = logging.getLogger()
logger.setLevel(logging.INFO)
region = os.environ['AWS_REGION']
cfg = botocore.config.Config(retries={'max_attempts': 0})
def lambda_handler(event, context):
    logger.info('starting loading')
    invokeLambda = boto3.client('lambda', region_name = 'us-east-1', config=cfg)  
    request = {'resource':'/bucketstatus/latest','path':'/bucketstatus/latest','httpMethod':'GET', 'requestContext': {'requestId': context.aws_request_id,'identity': {'userArn': context.invoked_function_arn}}}
    invoke_response = invokeLambda.invoke(FunctionName='loader_development',
                                           InvocationType='RequestResponse',
                                           Payload=json.dumps(request))
    print(invoke_response['Payload'].read())

logger.info('Process Complete')

But, "starting loading" is printing thrice so I think this script is getting invoked thrice. Previously only the loader_development lambda was being retried for which I set the value of max retry attempts to 0. (FYI: I have a cloudwatch event enabled for my trigger cron(0/30 7-9 * * ? *) so does the cloudwatch event also have a retry mechanism?) How do I disable this cloudwatch event from triggering my script more than once?

P.S. This code works if I don't have a scheduled cloudwatch event.

Getting the below error while executing lambda.
TypeError: Cannot read property '0' of undefined
at exports.handler (/var/task/index.js:8:43)

however we used the same index.js file and updated the mail IDs in SES section. Please suggest, for the error.

I am trying to get CloudWatchLogs filterLogEvents by sending parameters. some times it work and sends me the exact logs in that time, but for the different lambda function it returns empty events with next token.

parameters = {

'logGroupName' : metricFilter.logGroupName, 'filterPattern' : metricFilter.filterPattern ? metricFilter.filterPattern : "", 'startTime' : timestamp - offset, 'endTime' : timestamp };

i am retrying by sending parameters with next token but its still getting empty events. Does anyone has idea about it?

{
"events": [],
"searchedLogStreams": [],
"nextToken": "long text"
}

import * as AWS from 'aws-sdk';
var cwl = new AWS.CloudWatchLogs();

....


   var requestParams = {
      metricName: message.Trigger.MetricName,
      metricNamespace: message.Trigger.Namespace
    };
    console.log('describeMetricFilters', requestParams);
    const logEvents = await cwl.describeMetricFilters(requestParams, function(err, data) {
        if(err) {
          console.log('Error is:', err);
        } else {
          console.log('Metric Filter data is:', data);
          getLogsAndSendEmail(message, data);
        }
    }).promise();
    console.log("logEvents...", logEvents);

Log in CloudWatch
INFO Metric Filter data is: { metricFilters: [] }

I would love to see an SMTP option so this could be used in places where SES is not easily accessible like GovCloud.

TypeError: Cannot read property 'MetricName' of undefined at exports.handler (/var/task/index.js:14:36)

please suggest with this error when executing the script

Thanks
