Client fails with urllib3>=2.6.0 (AttributeError: 'HTTPResponse' object has no attribute 'getheader')

[nolmac]

urllib3 version 2.6.0 removed the deprecated getheader() method.

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).

Steps to Reproduce

• Install the generated python client.
• Update environment to urllib3>=2.6.0.
• Call an API method that processes response headers (e.g., create_upload_and_import_course_job).

Solution

• We need to update instances of HTTPResponse.getheaders() with HTTPResponse.headers.get() or pin urllib3 to <2.6.0 (though there are some security updates in 2.6.0 that we may want)
