+`CELERY_TASK_ALWAYS_EAGER: bool = True` will synchronously execute the celery tasks. This allows us to use things like `breakpoint()` to enter a debugger within the execution context of the task.
+
+Since the app currently uses the fastapi application config for celery config, add `CELERY_TASK_ALWAYS_EAGER=True` to the config class if needed. You don't need to run the worker, message broker, or result backend processes to debug your code. It will process the task within
