auth mode SSO not working with --oneshot flag

[torbenfritsch1234]

Hi,
we are trying to use the logsmith CLI with the --oneshot flag an ran into the following error:

[ERROR] MainThread auth_mode was neither key or sso.

even though our logsmith config does mention auth_mode: soo

dr-admin:
  color: '#BA34EB'
  team: myteam
  region: eu-central-1
  script: null
  auth_mode: sso

These are the logs:

$ logsmith --login dr-admin --oneshot

2025-12-15 11:14:22,456 [ERROR] MainThread   auth_mode was neither key or sso.

The strange part is, that the login was "successful".

Logging in without the --oneshot flag is successful:

logsmith --login dr-admin
