Discord 只发不收排障：Raspberry Pi 上从 intents 到会话生成的逐层回归

场景：Discord bot 可发送但收不到消息、无 MESSAGE_CREATE、无新会话。前置：Pi/ARM64 环境可访问日志，且 bot intents 已配置。步骤：先验证连接与发送能力，再验证 read API 与 session 生成链路，最后做版本与状态清理回归。关键命令：systemctl status、sessions_list。验证：用户消息可触发会话并回复。风险：误判为 token 问题导致反复重建 bot。

Prerequisites
  • Discord bot token is valid and required intents (including Message Content) are enabled in portal.
  • You can run diagnostics on Raspberry Pi host and inspect gateway service logs.
Steps
  1. Confirm bot login and outbound send path first (service status + send test).
  2. Use message-read path to verify inbound messages are visible at API layer.
  3. Check whether group sessions are created after inbound messages; if zero, focus on event handler path.
  4. Restart gateway, clear stale state/cache carefully, and retest with a fresh mention message.
  5. Only then consider bot recreation/version upgrade as last resort.
Commands
systemctl --user status openclaw-gateway
openclaw gateway restart
openclaw gateway status
Verify

A user mention triggers MESSAGE_CREATE handling and creates a live group session with reply.

Caveats
  • Do not over-clean runtime state without backups; excessive cleanup can remove useful diagnostics.
  • ARM64-specific runtime/event differences may require version-specific fixes（需验证）.
