doccano-client does not support urllib3 2.0.0

[baruch11]

How to reproduce the behaviour

I use poetry in my project. I just added doccano-client ("poetry add doccano-client"). My pyproject.toml looks like

[tool.poetry]
name = "poetry-demo"
version = "0.1.0"
description = ""
authors = ["CHARLES-HENRI PRAT"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.10"
doccano-client = "^1.2.8"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

And then when I just run python -c "import requests_toolbelt" I get this error
ImportError: cannot import name 'appengine' from 'urllib3.contrib' (/Users/charlesprat/RepoGit/poetry-demo/.venv/lib/python3.10/site-packages/urllib3/contrib/init.py)

Quick Fix

If I put a constraint on urllib3 version (poetry add urllib3@1.26), the error disappears.

Your Environment

• Operating System: Mac OS 14.1.1 (23B81)
• Python Version: 3.10
• Package Version: 1.2.8

The following version bumps are required For compatibility with urllib3 2.0:

requests-toolbelt (0.9.1 -> 1.0.0)
vcrpy (4.3.0 -> 4.4.0)

For me, it was types-requests floating up which prompted this issue:

poetry show urllib3
 name         : urllib3                                                                
 version      : 2.1.0                                                                  
 description  : HTTP library with thread-safe connection pooling, file post, and more. 

required by
 - requests >=1.21.1,<3
 - responses >=1.25.10
 - types-requests >=2

Is this fixed? Today I ran into an urllib3 2.5.0 related error with the latest doccano_client on a clean conda env:
ImportError: cannot import name 'appengine' from 'urllib3.contrib' ([...]/miniconda3/envs/dokano/lib/python3.13/site-packages/urllib3/contrib/__init__.py)

I managed to get it to work by installing urllib3==1.26.20 so maybe that should just be added to the requirements in pyproject.toml
I also tried urllib3==1.26.0 since that was what the "quick fix" suggested, but that version did not work.
