Incompatible with urllib3 >= 2.6.0: HTTPResponse.getheaders() and getheader() have been removed

[Nam-kyu]

Summary

sendbird-platform-sdk-python is incompatible with urllib3 >= 2.6.0 due to the use of the removed HTTPResponse.getheaders() and HTTPResponse.getheader() methods.

Environment

• Python version: 3.x
• urllib3 version: 2.6.0
• sendbird-platform-sdk version: latest

Error

When using urllib3 >= 2.6.0, the following error occurs:

AttributeError: 'HTTPResponse' object has no attribute 'getheaders'
# or
AttributeError: 'HTTPResponse' object has no attribute 'getheader'

Root Cause

The HTTPResponse.getheaders() and HTTPResponse.getheader() methods were deprecated in urllib3 2.0.0 and have been removed in urllib3 2.6.0.

From the urllib3 2.6.0 changelog:

Removed the HTTPResponse.getheaders() method in favor of HTTPResponse.headers. Removed the HTTPResponse.getheader(name, default) method in favor of HTTPResponse.headers.get(name, default).

Suggested Fix

# Before
response.getheaders()
response.getheader(name, default)

# After  
response.headers
response.headers.get(name, default)

Workaround

Until this is fixed, pin urllib3 to a version below 2.6.0:
