Research direction

Start by tracing the Codex CLI conversation request and JSON deserialization path after an image is sent, focusing on handling of the image_url message type. Reproduce the Windows sequence in the issue, then verify that subsequent text requests either deserialize successfully or that the conversation can recover without starting over.

Description

bug CLI session windows-os

复现步骤

  1. 在对话中发送一张图片

  2. 继续发送文字消息

  3. 每次请求返回错误：Failed to deserialize the JSON body into the target type:
    messages[49]: unknown variant image_url, expected text
    at line 1 column 262721

  4. 只能放弃当前对话，新建对话

期望
  • 支持 image_url 消息类型，或
  • 提供恢复机制（跳过/清理坏消息）
环境
  • Codex CLI 桌面版 (Windows)
  • 消息类型 image_url 被反序列化器拒绝
