This update modifies the error handling mechanism in the REST API meta fields functionality. Instead of halting execution and returning on the first encountered error, it now collects all errors in a WP_Error object and continues execution. Thus, this enhancement enables handling and displaying of multiple errors in a single response, improving the debugging process.
