V11: Database Backup using cron job Issue.

[YogendrasinhChavda]

Hello,
Good Afternoon!

When I am trying to take the databack backup of the instances from the server database it gives traceback and database backup is interrupted.
First of all, I installed module "saas_server_backup_ftp" in the server database and configured database backup related configuration from the menu: Settings => General Settings in my local system.
When I am trying to run Cronjob ( Backup SaaS Databases Scheduler ) to take the database backup It gives the traceback.

I already installed lib. in my local system:

sudo pip3 install wdb
sudo pip3 install wdb.server

Below is the traceback logs :

We fixed it temporarily by the comment the one line in "saas_server_backup_ftp" module.
File : models => saas_server.py
method: def _transport_backup(self, dump_db, filename=None):
line number : 52
Comment line : import wdb; wdb.set_trace()

Can anyone help me how can I resolve this issue permanently?

Thanks in advance.
