Error creating a Notification

When I try and create a notification for entering a geofence, I receive the following ERROR.

Invalid parameters or constraint violation
Invalid column name 'notificators'. - SQLServerException (... < QueryBuilder:480 < DataManager:458 < BaseObjectManager:90 < ...)

I am running the latest version of Traccar.

Looks like your database schema is out of date.

I am running MS SQL.
Is there a procedure for fixing the schema?

alter table dbo.tc_notifications
add notificators varchar(128) null

Thanks Arkom, that worked nicely.
