Hi,

On development, the cron job runs fine and takes about 20 minutes, but on production it finishes instantly without doing any work and the expected log message never appears. The cron used to run but stopped after changes were made to the odoo.conf file. Reverting the configuration didn’t fix the problem, and no errors show up in the logs or the UI.

The most likely causes are that the cron record is no longer correctly linked to the model, the model is not imported or loaded properly, the cron is running under a user with insufficient permissions, the cron registry cache has not refreshed, or the cron record itself has become corrupted.

To debug, you should check the scheduled action in Settings → Technical → Automation → Scheduled Actions to confirm the model and code are correct. You can also test in Odoo Shell whether the model orgamax_sync exists and whether calling sync_customers() directly works. If it does, the issue lies in the cron link; if not, the model may not be loaded. Changing the cron user, forcing a module reload with -u, or deleting and recreating the cron are recommended next steps.

In summary, the issue comes down to the cron record not being correctly tied to the model or method in production. Recreating or updating the scheduled action so it points properly to orgamax_sync.sync_customers should resolve the problem.

Hope it helps
