PHP function error handling

If a handler reports a PHP function runtime or loading error, the runtime environment automatically captures the error and returns a JSON document with details of the error type, text, and location in the response. For more information about the JSON document format, see Calling a function.

The error data is also written to the execution log. You can view it using the Yandex Cloud CLI or the management console.
