From 35f80a9875f1ee297e1c8054e737fc32a923071b Mon Sep 17 00:00:00 2001 From: Alexander Trakhimenok Date: Mon, 27 Jul 2026 09:54:27 +0000 Subject: [PATCH] fix(tgbotapi): webhook inline responses and chunked response bodies ReplyToResponse wrote 'TelegramMethod=' in the urlencoded webhook reply; the Bot API expects 'method=', so inline responses were silently ignored (by Telegram and by test emulators alike) and every reply fell back to direct API calls. MakeRequest skipped reading bodies without a Content-Length header (chunked responses), unmarshalling nil bytes. Found by chatwright e2e for the chess extension: the emulator parses the inline response exactly as Telegram documents it.
