Ensure all required extensions (ycommercewebservices, commercefacades, commercewebservicescommons, etc.) are included in your localextensions.xml.

Check if commercewebservices requires additional dependencies that might be missing.

Verify if the commercewebservices extension conflicts with any existing configurations.

Check local.properties for any missing or misconfigured API-related settings.

If you're migrating from an older version, check whether commercewebservices has breaking changes or requires updates in project.properties.
