Error on systemctl status chirpstack-application-server

Hello, this is my first post on the forum i hope i will give you the right informations…
For a project i have to create a lorawan using chirpstack. This is impossible for me to launch the -application-server, i did every manipulations i’ve seen on tutorials, searching on forum and so on… I have a postgresql database witch seems connected with chirpstack-network-server i copy / past the line in application-server.toml file, generate a jwt key, try to reinstall application-server, try to drop and recreate database… nothing works

journalctl gives

[edit 1]
chirpstack-application-server configfile gives me a file configuration witch is diffrent than the one in /etc/…/…toml i am on

[edit 2]
When i try
pi@raspberrypi:~ $ sudo chirpstack-application-server --config /etc/chirpstack-application-server/chirpstack-application-server.toml
INFO[0000] starting ChirpStack Application Server docs=“https://www.chirpstack.io/” version=3.8.0
INFO[0000] storage: setting up storage package
INFO[0000] storage: setup metrics
INFO[0000] storage: setting up Redis pool

INFO[0000] storage: applying PostgreSQL data migrations
FATA[0000] setup storage error: storage: applying PostgreSQL data migrations error: Unable to create migration plan because of 0002_node_frame_log.sql: unknown migration in database

but chirpstack-application-server still gives me a file configuration without the right database dsn.

I did a mistake seeing " ns and as " on db… i must use 2 diffrent databases…
