Return "Sorry, there was a problem with the app."

I have a weird mistake about this. I have completed the custom intent to donating shortcuts to call my back-end services in the handle method of extension. It all goes well. But happened a wrong when the language is Japanese.


When the interactive language is English, everything works well,even Chinese, he is going on.


when the interaction language is Japanese, call the shortcuts. Return Sorry, there was a problem with the app.(Translation from Japanese)


I can't get any error messages, what am I missing? I finished localization

As a supplement, no matter what language, They entered the confirm method, because when I debug the extension, I saw the log I printed,and the response value of the completion is the same. I am very confused
