S3 backup issue

I got this message while trying to backup using s3 backup

I’m using the system by AWS cloud bitnami, version 13.9.2

Error message: Traceback (most recent call last): File “/opt/bitnami/apps/erpnext/htdocs/frappe-bench/apps/frappe/frappe/integrations/doctype/s3_backup_settings/s3_backup_settings.py”, line 80, in take_backups_s3 validate_file_size() File “/opt/bitnami/apps/erpnext/htdocs/frappe-bench/apps/frappe/frappe/integrations/offsite_backup_utils.py”, line 103, in validate_file_size file_size = get_file_size(latest_file, unit=“GB”) File “/opt/bitnami/apps/erpnext/htdocs/frappe-bench/apps/frappe/frappe/integrations/offsite_backup_utils.py”, line 73, in get_file_size file_size = os.path.getsize(file_path) File “/opt/bitnami/python/lib/python3.7/genericpath.py”, line 50, in getsize return os.stat(filename).st_size TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType
