From ab4f82f6646bcd278744ddc7606598f48005c9fb Mon Sep 17 00:00:00 2001 From: Markus Windhager <44254831+rb-mwindh@users.noreply.github.com> Date: Fri, 17 Oct 2025 15:24:35 +0000 Subject: [PATCH] fix: add undici ProxyAgent support for GitHub Enterprise Server behind proxies - Add undici ProxyAgent as dispatcher in custom fetch function - Maintain backwards compatibility with existing agent option - Add comprehensive unit tests for proxy functionality - Fix proxy support for GitHub Enterprise Server environments Fixes issue where @semantic-release/github cannot connect through corporate proxies due to undici's fetch implementation not respecting the agent option. The solution provides both legacy agent support and new undici ProxyAgent dispatcher for modern Octokit versions that use undici as their fetch implementation. --- lib/octokit.js | 15 +++-- package-lock.json | 9 +++ package.json | 1 + test/octokit-proxy-integration.test.js | 89 +++++++++++++++++++++++++ test/to-octokit-options.test.js | 90 ++++++++++++++++++++++++++ 5 files changed, 200 insertions(+), 4 deletions(-) create mode 100644 test/octokit-proxy-integration.test.js diff --git a/lib/octokit.js b/lib/octokit.js index 6bb6db1c..264eaa2b 100644 --- a/lib/octokit.js +++ b/lib/octokit.js @@ -14,6 +14,7 @@ import { throttling } from "@octokit/plugin-throttling";
