Yes it's not being called, and the reason is this: https://github.com/encode/starlette/issues/486 Short version: by default an exception raised during that phase is silently swallowed! You can avoid the swallowing by adding `lifespan="on"` to the call to `uvicorn.run()`. When I did that here: `uvicorn.run(ds.app(), host=host, port=port, log_level="info", lifespan="on")` The server failed to start with this error: ``` INFO: Started server process [68849] INFO: Waiting for application startup.
