message tool: filePath media upload fails with ‘Channel is unavailable: telegram’ in 2026.3.23-2
증상
Version: OpenClaw 2026.3.23-2 (7ffe7e4)
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
Direct Telegram Bot API calls via curl work perfectly:
curl -X POST 'https://api.telegram.org/bot<token>/sendDocument' \
-F chat_id=<id> \
-F document=@/path/to/file.pdf
This confirms the Telegram API and bot token are fine — the bug is in OpenClaw’s message tool pipeline.
