Issues with Celery Worker in ECS After Upgrading from 2.24.2 to 2.28.2: ContentDisallowed Pickle Error

Hello everyone, I just upgraded my dev env from 2.54.2 to 2.58.2 and I started having issues with celeryworker container in ECS. I found the following error in cloudwatch logs

CRITICAL [celery.worker:207] Unrecoverable error: ContentDisallowed(
  'Refusing to deserialize untrusted content of type pickle (application/x-python-serialize)'
)

I also found a PR to Remove pickle, but to be honest, I have not found what should I do next to fix this error, maybe something related to redis? Thanks for your help
