Hi @Qiwen-Yu ,
Thank you for your work.
I checked the file, and several problems made the program could not run. Please check:

• It should be using Newtonsoft.Json.Linq;
• The KeyValuePair<string, JToken> is not right, you can use jObj["input"] to get the value
• missing; in line 66
• you forget to initialize the inputname variable.
  Would you please fix the program.cs file according to these problems.
  Thank you very much,
