Fix AttributeError

✅ Solution

This AttributeError in Celery often arises when a string is incorrectly passed where a module or class is expected, particularly within Django settings or task definitions. Ensure that settings like `CELERY_TASK_SERIALIZER`, `CELERY_RESULT_SERIALIZER`, or task imports are referencing actual module or class objects, not string representations. Review your Celery configuration and task definitions, replacing string literals with direct references to the correct module or class.
