To force Magento to use the full product path, you need to change the settings in the Magento backend. Here's how:
- Log in to the Magento backend
- Go to Stores > Settings > Configuration
- In the left-side menu, navigate to Catalog > Catalog
- Under the Search Engine Optimizations section, set "Use Categories Path for Product URLs" to "Yes".
- Save the changes by clicking the "Save Config" button.
This will ensure that Magento uses the full product path in the URLs, including the categories, for your products.
