I'm encountering an issue with my Django project deployment on Railway. The deployment fails with the following error:

AttributeError: module 'collections' has no attribute 'Iterator'

I have already modified the Django source code to replace collections.Iterator with collections.abc.Iterator, but the issue persists. I've tried clearing caches locally, but since the problem seems to occur on the server side, I suspect there might be an issue with cached files or the deployment environment. Please advise on how to resolve this issue or how to ensure the cache is cleared on the server.

Here are the logs and additional details:

Thank you for your assistance.
