The e - commerce payment page displays an error

The product information is shown as None, and the image and its url cannot be displaye,How can I solve this problem;

Can you send us the log file contents? /edx/var/log/ecommerce/edx.log

@HertZPY, this information is retrieved by the ecommerce service from the LMS via the course-discovery service. For that to work, the sites/site configuration and partners have to be configured in ecommerce and the course-discovery service and the refresh_course_metadata management command in the course-discovery service has to be run periodically.

Please check and verify that this is the case.
