Seafile-CE-7.1.2 - Error when migrating from sqlite to mariadb

Hi! I did the migration from sqlite to mariadb in debian 10 finding an error in ccnet-db.sql and a lot of errors in seahub-db.sql in all the table creation statements, after correcting them, perform the migration correctly, but I have the next error in seahub.log:

[ERROR] seahub.notifications.utils:97 update_notice_detail Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

Debian 10
MariaDB 10.3.22
Seafile 7.1.2

Solved by cleaning the table notifications_usernotification
