Unable to import module lambda function No module named pymongo for mongodb with python in aws lambda

Question

I am getting exception in AWS lambda function as below for python program with MongoDB:-

{
  "errorMessage": "Unable to import module 'lambda_function': No module named 'pymongo'",
  "errorType": "Runtime.ImportModuleError"
}

But Pymongo added as a layer in lambda & also associated with the lambda function.

Hi@pradip,

I think you need to import some modules in your lambda script. Or you didn't create the lambda function. It will ask for a Lambda function handler. You have to name it as your python_filename.lambda_handler.

Hope this helps!!

Thanks!

Hi @MD,

Thanks for your reply.

I have checked the file name and handler name both are correct. Sharing the lambda function name & file name also for your reference

File Name : lambda_function

Function Name : lambda_handler

and final name as : lambda_function.lambda_handler

Hi@pradip,

Ok. Can you share your script that you are trying to run in the lambda function?

import json
import pymongo
import requests
import os
from bs4 import BeautifulSoup
from pymongo import MongoClient
import datetime
db_userName = “*******”
db_password = “********”
db_name = “******”
db_host = “********”
db_port = “*******”
mongo_link = "mongodb://" + db_userName + ":" + db_password + "@" + db_host +":"+ db_port
def lambda_handler(event, context):
    rss_news_parser()
    return {
        'statusCode': 200,
        'body': json.dumps('Scrapping Done!')
    }
def rss_news_parser():

Hi@pradip,

Your code seems totally fine. But your mongo_url seems not ok. Do one thing, just go to your database and copy the URL and paste it into your code.
