HI,

After upgrading zabbix from 5.2 to 5.4 using the debian repo, zabbix won't start.

I have these messages in the logs:

18681:20210525:113607.019 query [txnlev:1] [insert into widget_field (widget_fieldid,widgetid,type,name,value_int,value_str,value_itemid,value_graphid,value_groupid,value_hostid,value_sysmapid) values (479,59,0,'show_lines',1,'',null,null,null,null,null)]

Don't know what to do to allow the database migration.

Thanks,

Mathieu
