Hello Experts

I'm facing a error while executing database backup with filestore at /database/manager. This is the error:

2021-06-25 14:36:27,815 2221 ERROR databaselive odoo.addons.web.controllers.main: Database.backup
Traceback (most recent call last):

Note: I can create backups with dump format (without filestore)

can someone help with this error?
