PHP function error handling

If a handler reports a PHP function execution or loading error, the runtime automatically catches the error and returns a JSON document with details of the error type, text, and location. For more information about the JSON document format, see Invoking a function.

The error info is also written to the execution log. You can view the log via the Yandex Cloud CLI or the management console.
