traccar with postgresql update server error

Hi,
I installed traccar server with a postgresql database using docker.
and it' s working fine but when i try to update my server like changing the speedUnit it always failed with this error

ERROR: column "announcement" of relation "tc_servers" does not exist
  Position: 106 - PSQLException (... < QueryBuilder: 480 < DataManager: 464 < PermissionsManager: 434 < ...)

any help?

Looks like you haven't upgraded your server correctly.

Hi Anton,
thank you for replying
so as i said i'm using traccar inside docker container with the official Dockerfile.
and this is my docker-compose.yml file :
https://github.com/khiareddine123/traccar-postgres/blob/main/docker-compose.yml
i didn't interstand exactly what is wrong with my server

Your database schema is incorrect.

Hi Anton,
Thank you for explain,
I didn't touch my database,
so do you have any idea how to fix it ?

You have to run the liquibase changelogs or fix it manually.

Hi Anton,
I have no idea about liquibase.
But i fixed it by creating an announcement table inside my database.
Thank you for helping

Not sure how that fixed it because the issue was missing column, not a table.
