Chirpstack event topic {{application_id}} null problem

ChirpStack (v4) Setup and configuration
1

Hi everyone,

I have a problem with event topic configuration from chirpstack.toml and {{application_id}} variable. It seems it is null because from mosquitto log we see:

Received PUBLISH from chirpstack (d0, q0, r0, m0, 'application//device/00078137000152799/event/up', ...)

chirpstack.toml definition:

[integration]
  enabled=["mqtt"]

  [integration.mqtt]
    event_topic="application/{{application_id}}/device/{{dev_eui}}/event/{{event}}"
    command_topic="application/{{application_id}}/device/{{dev_eui}}/command/{{command}}"

What could be the problem?
