Agent not working properly on SQL Server 2019 Linux based container

[Massimo Giambona]

Cannot setup Sql Server Properties

1. Run an image docker run -d -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=P@ssw0rd!" -e "MSSQL_AGENT_ENABLED=true" -p 9001:1433 --name sql1 --hostname sql1 mcr.microsoft.com/mssql/server:2019-latest
2. Open SSMS
3. Right click on Agent -> Properties
4. Select Alert System tab and click ok, raise error A severe error occurred on the current command. The results, if any, should be discarded. (.Net SqlClient Data Provider)
5. Same error if you generate the script

GO
EXEC msdb.dbo.sp_set_sqlagent_properties @email_save_in_sent_folder=1
GO

Cannot raise alert

1. Create a new alert for error 21 (but any is good)
2. Add an operator with a fake email
3. Open a query an run RAISERROR ( 'Whoops, an error occurred.',21,1)WITH LOG
4. The alert is never triggered (See history)
5. No Log is written

UPDATE

I see that files under /var/opt/mssql/log belong all to root, changing its from root:root to mssql:root the log node is now visible on SSMS
