类型不匹配？

Workstation中的Group Chat示例，导出的代码：
flow = None
flow = Msg(content="Hello every one", name="User", role="user")
…………
pipeline_5 = WhileLoopPipeline(
loop_body_operators=[pipeline_6], condition_func=lambda *args: True
)
…………
flow = pipeline_5(flow)

pipeline.py 中：
class WhileLoopPipeline(PipelineBase):
…………
def __call__(self, x: Optional[dict] = None) -> dict:
return whilelooppipeline(
loop_body_operators=self.loop_body_operators,
condition_func=self.condition_func,
x=x,
)

看这里这个__call__的定义中接收的参数类型，为什么pipeline_5能接受flow（Msg对象）啊。

That's correct. We found that WhileLoopPipeline often created workflows that were difficult for developers to debug and control.

For this reason, we have deprecated it in the latest version. The recommended approach is now to construct the workflow explicitly, which provides greater clarity and makes the logic easier to follow.
