Exception: Trying to access array offset on value of type null in /vendor/hprose/hprose/src/Hprose/Client.php:383 的排查分析
1、接口响应：Trying to access array offset on value of type null。如图1
图1
2、由于此接口基于 Hprose 请求 RPC 服务端。查看相应的运行日志。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。如图2
