openclaw - 💡(How to fix) Fix message tool: text param ignored when both text and message are provided (Feishu channel)

Bug Description

When calling the message tool with both text and message parameters simultaneously, the Feishu channel only displays the value of message, ignoring text. This appears to be a regression in the Feishu plugin (v2026.5.20).

Reproduction Steps

Call the message tool:

{
  "action": "send",
  "channel": "feishu",
  "target": "user:ou_xxx",
  "text": "This is the long body that should be displayed",
  "message": "Short summary ✓"
}

Expected: Feishu displays the text value. Actual: Only the message value ("Short summary ✓") is displayed.

Schema Analysis

The tool schema requires both fields:

• text — "must have required properties text"
• message — "must have required properties message"

But when both are present, message overrides text in the actual delivery.

Evidence

1. Call with only message (no text): Validation failed — "text: must have required properties text"
2. Call with both text + message: Returns ok: true, but delivered message on Feishu is only the message param value

Verified via Feishu message API — the delivered message content field equals the message param, not text.

Environment

• OpenClaw version: 2026.5.1
• Feishu plugin (openclaw-lark): v2026.5.20 (upgraded from v2026.5.7 — worked correctly before upgrade)
• Channel: feishu
• Platform: macOS arm64
