Here are some issues and suggestions for improvement in your code:

Issues:

1. Undefined chatRecord: The variable props.chatRecord is being used without checking if it's defined, which could lead to an error or incorrect behavior.

2. Lack of Error Handling: If execution_details or specific nodes like start-node don't exist, the rest of the image/document/audio/video/other lists will be empty.

3. Overloading Message Parameters: The sendMessage function seems to accept multiple optional parameters (re_chat, image_list, etc.), but not all fields may always be populated. Consider handling this more robustly within each use case.

4. Repetition of Logic: The logic for constructing the objects that contain image/document/audio/video/other lists can be refactored into a helper function or class property to reduce redundancy.

These changes make the code cleaner, safer, less repetitive, and easier to maintain. They also address potential undefined errors when dealing with data that might be absent from certain stages.
