Additional information

extent analysis

TL;DR

The issue might be resolved by adjusting the message formatting or handling in the OpenClaw to Telegram messaging chain, ensuring both image and text are properly sent and displayed.

Guidance

  • Verify the message structure being sent from OpenClaw to Telegram, checking if the text is correctly attached or referenced alongside the image.
  • Review the OpenClaw documentation and configuration for any options related to message formatting, especially concerning multimedia messages.
  • Check the Telegram API documentation for any specific requirements or limitations on sending messages with both images and text.
  • Test sending a message with text and an image directly from the Control UI to Telegram to isolate if the issue lies in the Agent's message generation or the messaging pipeline.

Example

No specific code example can be provided without more details on the OpenClaw or Agent's messaging implementation.

Notes

The solution may depend on the specifics of the OpenClaw and Telegram APIs, as well as the exact configuration of the messaging pipeline. Further investigation into the message handling and formatting is necessary.

Recommendation

Apply workaround: Adjust the message formatting in the OpenClaw to ensure compatibility with Telegram's requirements for messages containing both images and text. This approach is recommended as it directly addresses the observed issue without requiring version upgrades or significant infrastructure changes.
