GetResponse API显示错误，但工作JSON

我有代码从GetResponse添加一个联系到一个活动。该脚本正在工作，因为它将联系人添加到GetResponse，然而，它一直显示这2个错误，并在我的服务器上留下一个错误日志。如果可以，请帮我修正这两个错误。

下面是我得到的2个错误....

警告:在autoresponders/getresponse/jsonrpclient .php的第242行中，输入:" (ASCII=1) state=0 "中的意外字符

严格的标准:只有变量应该在autoresponders/getresponse/add.php的第29行通过引用传递联系人添加

代码如下:

. php:
