Product Sync Not Working Automatically – Missing Access Token Alert

Dear Support Team,

I have configured the plugin to automatically sync products daily, but the sync is not working as expected. Today, when checking the logs, I noticed that the products have not been synchronized. The logs shows the following message:

2025-07-08T03:08:22+00:00 ALERT Missing access token.

In the plugin settings, everything appears green and it says:
Next schedule: July 12, 2025 4:00:00 AM.

There are no other error messages displayed, but I have confirmed that the products are not syncing automatically. Could you please assist me in resolving this issue?

Thank you in advance for your help.
