AWS Lambda import error: Unable to import module "lambda_function"

I am trying to run a simple program in AWS Lambda. However, it is failing with DEFAULT_CIPHERS error. When I run the following program it fails with error ...unable to import lambda function:

import json
import boto3
import os
import requests

def lambda_handler(event, context):
    file = '2011-02-12-0.json.gz'
    download_res = requests.get(f"https://data.gharchive.org/{file}")
    print(f"Files downloaded successfully - Filename: {file}")
    os.environ.setdefault('AWS_PROFILE', 'myid')
    s3 = boto3.client('s3')
    upload_res = s3.put_object(Bucket='my-demo-bucket3', Key=file, Body=download_res.content)
    print("Files Uploaded successfully")
    return upload_res

Error:

Response
{
  "errorMessage": "Unable to import module 'lambda_function': cannot import name 'DEFAULT_CIPHERS' from 'urllib3.util.ssl_' (/var/task/urllib3/util/ssl_.py)",
  "errorType": "Runtime.ImportModuleError",
  "requestId": "5d82baed-2ee6-41cd-a8e7-d24a59061dbc",
  "stackTrace": []
}

Can anyone please help me sort this out.
Thanks.

The issue is in the versioning of the packages. The difference in these 2 codes that makes the problem is boto3. There's an open issue on GitHub related to this.
A solution, as several people wrote there would be to pin down the version of urllib3

You can put something like this in your requirements.txt

requests
urllib3<2

The second option is to pin down the requests package to 2.29.0, as 2 guys mentioned this fixed issue with their Lambda functions.

To track the progress of this, you can check the issue in Github
