urllib3.response.HTTPResponse.getheaders() is deprecated in urllib3

[StefosGeo]

Hi , I noticed that getheaders() is used when working with urllib3.response.HTTPResponse. This method is deprecated in urllib3 and raises a DepricationWarning error. Maybe it worth considering using headers property

This was pointed out here #226 and their problem lies on the code generator. I'm also waiting for this update to remove a lot of log warnings. Any updates on this issue?

Hey everyone! We’re aware of the issue and are currently working on a fix.

@alzheltkovskiy-hubspot fyi, it was removed in urllib3 v2.6.0: https://urllib3.readthedocs.io/en/stable/changelog.html

Currently, HubSpot sdk not working, consider to specify urllib3 version <2.6.0

requirements should reflect that this repo breaks on urllib > 2.5

Hi everyone, thanks for the updates and for highlighting the change in urllib3 v2.6.0.

We are currently working on a new version of the SDK where this issue — along with other deprecated or removed API calls — will be addressed.

In the meantime, specifying urllib3 < 2.6.0 is indeed a temporary workaround.

Thanks for your patience, and we’ll share more updates soon.

I'd suggest immediately reflecting this dependency in your requirements.txt. Right now the repo resolves into a broken state with pip install, and it's remediated with that single line change.

Pinning to the old version is also not ideal at all. So we're stuck with it either being broken or having a known vuln.

urllib3 2.5.0   CVE-2025-66418 2.6.0
urllib3 2.5.0   CVE-2025-66471 2.6.0

@alzheltkovskiy-hubspot glad to hear- is there an ETA for the update?

If you update urllib3 to run version 2.6.1 this should solve the issue.
