英文:
AWS Lambda import error: Unable to import module "lambda_function"
问题
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.

问题出在软件包的版本问题。这两段代码的不同之处在于导致问题的boto3。在GitHub上有一个与此相关的已打开问题。解决方法，正如几个人在那里写的那样，是锁定urllib3的版本。可以在你的requirements.txt中添加类似以下内容：
requests
urllib3<2
第二个选项是将requests软件包锁定到2.29.0版本，就像有两个人提到的，这可以解决他们Lambda函数的问题。
要跟踪这个问题的进展，可以查看Github上的问题。
英文:
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
