Changeset 45809 for trunk/src/wp-includes/rest-api/class-wp-rest-server.php

Timestamp:

Message:

REST API: Do not send response body if status is 204 or body is null.

Status code 204 should indicate no response body is sent. Previously, a "null" string was sent, which MacOS Safari would try to parse as JSON and thereby fail to complete the request.

Props TimothyBlynJacobs, andizer, matthias.thiel.
Fixes #43691.
