This error occurs due to a temporary issue in the eBay synchronization process. In case the synchronization gets stuck with this message, follow these steps:

1. Refresh the module’s page.
2. Start the synchronization again.

In many cases, the module will recognize the problem and successfully complete the ongoing procedure. However, in some cases, the procedure may not conclude correctly, and the error message may persist.

To resolve this situation, you can follow these steps:

1. Go to the DEBUG mode of the module.
2. Find the “Svuota storico job” (Clear job history) button and use it to reset any stuck tasks.
3. Start a new synchronization.

If the error message appears again during a new synchronization, it could be due to temporary issues on eBay’s side. In such a case, it is recommended to wait for a while and try again later. Alternatively, you can use standard synchronization methods if needed.
