Hello,
I have app with errors handlers. I have handler for error.runtime, error.noresources.asr
But when I got subj error then I have "You have technical difficulties" message.
How to catch it? Which error handler should I have?

I have the following error at "Log Viewer":
Application errors occurred for application 0:Yandex, Session ID rshb-epm-2019337140145-1, [Recognizer returned ASRError]

Similar error is with TTS as well:
I got the following:
"Application errors occurred for application 0:TestUniMRCP, Session ID rshb-epm-2019337204001-1, [Error: 007 cancelled]"

How to catch it at error handler?

Best regards, Dmitry

You can try to catch the error by using the catch item in the Approot.

I am doing this. But which event need to use for such error?
I use error.runtime, error.noresources.asr These events don't catch this error.

You should check the mpp log to see what exactly occurred.
