During setting up the Shopping insights bestseller report you might get the following error:
Error: Failed to find valid credential. Account not set up to use Google merchant center transfer service.
The error indicates that the account you are attempting to use for setting up your report has not previously utilized the Merchant center transfer service. To extract the potentially large number of products from a Merchant center account, we rely on Google's data transfer service. This service requires you to log in at least once before it can be accessed by Alvie.
Follow the steps in the below video to fix the issue:
You only need to create one test configuration and then delete it.
Make sure that your test transfer points to a dataset located in the EU, not the US!
After resolving an error, you can follow these steps:
Go to Data & reporting → Reporting solutions.
Identify the required report.
Click on the 'More' menu (three dots on the right side of the card).
Choose 'Run now' to initiate the report once again.
If you encounter any further issues or need additional assistance, please don't hesitate to reach out to the Alvie support team.
