执行`flowinsight run`,对应执行到: https://github.com/antgroup/flow-insight/blob/main/sdk/flow_insight/cli.py#L42-L56 ` app = create_app()` 这里create_app对应代码: https://github.com/antgroup/flow-insight/blob/main/sdk/flow_insight/api/fastapi_api.py#L583-L586 ``` def create_app(): """Create a FastAPI application instance.""" server = FastAPIInsightServer() return server.app ``` 由于没有执行到run函数: https://github.com/antgroup/flow-insight/blob/main/sdk/flow_insight/api/fastapi_api.py#L112-L121 导致_process_record_queue函数没执行,所有emit_record无法将数据发送到engine,即: https://github.com/antgroup/flow-insight/blob/main/sdk/flow_insight/api/fastapi_api.py#L108 `await self.engine.record_event(record)` 始终执行不到。 由于上面问题,运行demo会发现前台永远是空的。
