hello i'm new to lavinmq

i'm installing lavinmq on my ubuntu laptop for experiment, but i get this error log when starting lavinmq service
(found from command => journalctl -xeu lavinmq.service)

Outdated schema version 0 for /var/lib/lavinmq/42099b4af021e53fd8fd4e056c2568d7c2e3ffa8/97c1c36cf4b13e7f763f7ca5

after i delete the folder then restart, it works again, why this is happening ?
If my experiment run smoothly, i'm planning to replace rabbitmq with lavinmq on my production server

Hi @superdit

Which version of LavinMQ are you using?

Could you please provide the content of your /var/lib/lavinmq/42099b4af021e53fd8fd4e056c2568d7c2e3ffa8/97c1c36cf4b13e7f763f7ca5 folder?

i'm running lavinmq version 1.2.7
installed using ubuntu repository

sorry since i already deleted the folder I don't know what content inside the folder

but now. after I deleted it, inside this folder (/var/lib/lavinmq/42099b4af021e53fd8fd4e056c2568d7c2e3ffa8) i get only these files
definitions.amqp
.vhost

Okay, thanks.

Have you had any earlier versions of LavinMQ installed on your machine?

I'm not able to reproduce this on my machine at the moment. Could you please provide the following information:

1. What version of Ubuntu are you running?
2. What are the permissions for /var/lib/lavinmq ?
3. Steps to reproduce (what commands did you run)

Closing because of inactivity.

the same issue:

• FreeBSD 15.0-CURRENT amd64
