1. API response: Trying to access array offset on value of type null. See Figure 1.
2. Because this API requests the RPC server based on Hprose, I checked the corresponding runtime logs. Exception: Trying to access array offset on value of type null in /mcloud/www/channel-pub-api/vendor/hprose/hprose/src/Hprose/Client.php:383. See Figure 2.
