## Breaking Changes & Deprecations
- :warning: Breaking Changes :warning: Starting with Strapi v4.13.1, requests to the Content API using invalid query parameters will be rejected with an error response instead of being silently removed from the query. If you are seeing “Invalid parameter” errors in a Content API request, please ensure that every parameter in your query string is valid. If you need the previous behavior of filtering out invalid parameters, you will need to use a custom controller that only calls `sanitizeQuery` and not `validateQuery`. For more information as to why we made this change please see #17001
