dependency problem with urllib3>=2.0.0

[ds21194]

I'm trying to use this lib (toolbelt) with AWS lambda, and apparently boto3 does not support urllib3>=2.0.0:

https://stackoverflow.com/questions/76414514/cannot-import-name-default-ciphers-from-urllib3-util-ssl-on-aws-lambda-us Throwing the error in the link.

Is there a version of this lib that uses a lower version of urllib3, so I won't have this dependency colission? Thanks!

Hello, as far as I can tell, this library supports urllib3 1.26.x. Please reopen if you have evidence of the contrary.

Maybe I'm doing something wrong, but this is how I'm creating the AWS Layer:

`docker run -v "$PWD":/var/task "public.ecr.aws/sam/build-python3.9" /bin/sh -c "pip install -r requirements.txt -t logs:

`python/lib/python3.9/site-packages/; exit"

and I'm still getting this error: [ERROR] Runtime.ImportModuleError: Unable to import module 'post_messages': cannot import name 'DEFAULT_CIPHERS' from 'urllib3.util.ssl_' (/opt/python/lib/python3.9/site-packages/urllib3/util/ssl_.py)

I even tried to install with pip install --force-reinstall -v -r requirements.txt -t python/lib/python3.9/site-packages/; to make sure the right version of urlib3 is installed.

Worth to mention that when I installed only urlib3 1.26.7 this behavior didn't happen.

What do you think? @pquentin BTW- it happened both with versions 1.0.0 and 0.10.1, didn't check more.

Can you please post the full traceback, not just the cannot import name 'DEFAULT_CIPHERS' line? Nothing is pointing to requests-toolbelt right now.

You are right, I found the issue. I didn't notice my boto3 lib was outdated (3.10 instead of 3.27) Thanks for the help, much appreciation
