If `reason` is set to None, a regex search on it fails. This prevents the calling test from checking that the error is correct.\r\n\r\n```py\r\nTraceback (most recent call last):\r\n  File \"/Users/buildbot/buildarea/3.x.pablogsal-macos-m1.macos-with-brew/build/Lib/test/test_ssl.py\", line 5085, in test_preauth_data_to_tls_server\r\n    self.non_linux_skip_if_other_okay_error(wrap_error)\r\n    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^\r\n  File \"/Users/buildbot/buildarea/3.x.pablogsal-macos-m1.macos-with-brew/build/Lib/test/test_ssl.py\", line 5032, in non_linux_skip_if_other_okay_error\r\n    re.search('wrong.version.number', getattr(err, \"reason\", \"\"), re.I)):\r\n    ~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\r\n  File \"/Users/buildbot/buildarea/3.x.pablogsal-macos-m1.macos-with-brew/build/Lib/re/__init__.py\", line 177, in search\r\n    return _compile(pattern, flags).search(string)\r\n           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^\r\nTypeError: expected string or bytes-like object, got 'NoneType'\r\n```\r\n\r\nI'll send a  PR soon.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-126501\n* gh-126573\n* gh-126574\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/encukou","@type":"Person","name":"encukou"},"datePublished":"2024-11-06T14:11:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/126499/cpython/issues/126499"}
