PowerApps中的Chatbot连接

Question

我已经创建了QNA，Postman和连接，但是我已经陷入了应用程序，任何人都可以帮助我吗？

我使用以下代码 -

选择按钮

ClearCollect(chat,{id:0,name:"EmployeeFaqBot",text:"Welcome " &User().FullName &" ! Enter your Query"})

屏幕的OnStart

Collect(chat,{id:1,name:User().FullName,text:TextInput1.Text});
Collect(chat,{id:0,name:"EmployeeFaqBot",text:First(OPMS_Service.GenerateAnswer({question:TextInput1.Text}).answers).answer})


Collect(chat,{id:1,name:User().FullName,text:TextInput1.Text});
Collect(chat,{id:0,name:"EmployeeFaqBot",text:First(OPMS_Service.GenerateAnswer("application/json",{question:TextInput1.Text}).answers).answer})


Collect(chat,{id:1,name:User().FullName,text:TextInput1.Text});
Collect(chat,{id:0,name:"EmployeeFaqBot",text:First(OPMS_Service.GenerateAnswer({"application/json",question:TextInput1.Text}).answers).answer})

错误 -

＆＃34;参数数量无效＆＃34;在OnSelect按钮上。

我也试过以下代码

{{1}}

感谢。
