3 tests in tests/gateway/test_dingtalk.py::TestIncomingHandlerProcess fail with AttributeError: 'NoneType' object has no attribute 'from_dict' because ChatbotMessage is None when dingtalk-stream SDK is not installed.

Error Message

gateway/platforms/dingtalk.py

try: from dingtalk_stream import ChatbotMessage except ImportError: ChatbotMessage = None # <-- this happens when SDK is absent

Root Cause

# gateway/platforms/dingtalk.py
try:
    from dingtalk_stream import ChatbotMessage
except ImportError:
    ChatbotMessage = None  # <-- this happens when SDK is absent

_IncomingHandler.process() calls ChatbotMessage.from_dict(data) at line 1309 without guarding against None, raising AttributeError.

Fix Action

Fix

Tests should mock ChatbotMessage or use pytest.importorskip("dingtalk_stream").

Code Example

# gateway/platforms/dingtalk.py
try:
    from dingtalk_stream import ChatbotMessage
except ImportError:
    ChatbotMessage = None  # <-- this happens when SDK is absent
