I made a software to create listing for parts, then it publishes them under the general motorcycle parts category, every time it does though, it doesn't actually publish and i get this return message. Has anyone seen this before and does anyone know a fix?
Uploading 1 listing(s) to eBay [production]
[1/1] webapp_data\photos\6051d119-thermostat
Wrote upload_results.json
! {'step': 'publish', 'detail': 'All category candidates rejected by eBay.', 'attempts': [{'category': '179753', 'step': 'publish', 'code': 400, 'body': {'errors': [{'errorId': 25005, 'domain': 'API_INVENTORY', 'subdomain': 'Selling', 'category': 'Request', 'message': 'The eBay listing associated with the inventory item, or the unpublished offer has an invalid category ID.

Thank you for your post!
We would like to inform you that this error typically occurs when an invalid category ID is used. We recommend verifying that you are using the correct category ID by calling the Get Category Tree API from the Taxonomy API for the site where you intend to list the item.
For more information, please refer to the following documentation:
https://developer.ebay.com/api-docs/commerce/taxonomy/resources/category_tree/methods/getCategoryTre...
If you continue to experience the issue, we kindly ask that you submit a support ticket through the eBay Support Tickets page. Please include the request/response details along with the rlogId. This complimentary service will enable us to investigate the issue more thoroughly.
Once we have these details, we will be able to assist you more effectively.
Best regards,
eBay Developer Support
