Summary

Bug

Sending .opus audio files via the Feishu plugin fails with:

The type of file upload does not match the type of message being sent.

The plugin falls back to a text message like 📎 /path/to/file.opus.

Root Cause

In extensions/feishu/src/media.ts, sendMediaFeishu uses msg_type: "media" for both audio and video:

const isMedia = fileType === "mp4" || fileType === "opus";
msgType: isMedia ? "media" : "file"

But Feishu API requires:

• Audio (opus): msg_type: "audio"
• Video (mp4): msg_type: "media"

Ref: https://open.feishu.cn/document/server-docs/im-v1/message/create

Fix

// sendFileFeishu msgType type should include "audio"
msgType?: "file" | "media" | "audio";

// sendMediaFeishu: map file types correctly
const msgType = fileType === "opus" ? "audio" : fileType === "mp4" ? "media" : "file";

Reproduce

1. Generate an opus file
2. message(action=send, channel=feishu, filePath=workspace/file.opus)
3. Feishu returns type mismatch error
4. Falls back to text with 📎 prefix

Environment

• OpenClaw gateway on WSL2
• Feishu plugin (extensions/feishu)
• Node v24.13.1

Steps to reproduce

1. Generate an opus file
2. message(action=send, channel=feishu, filePath=workspace/file.opus)
3. Feishu returns type mismatch error
4. Falls back to text with 📎 prefix

Expected behavior

Opus files should be sent with msg_type: "audio" so Feishu renders them as playable voice messages, not file attachments or fallback text.

Actual behavior

Opus files are uploaded with file_type: "opus" but sent with msg_type: "media" (video type). Feishu rejects the mismatch, and the plugin falls back to sending a plain text message: 📎 /path/to/file.opus.
