Hi DaYoung,
This is not an error in your app, but the Mendix deployment system that is also developed in Mendix. The error comes from the deeplink module action called: ExecuteDeeplink. When this action fails, instead of creating a log message (what it should do) it shows a pop-up message to the user.
So, it's a bug in the deeplink module, but not from your app :).
Hi DaYoung,
ıt would be better if you may share more details about your structure and the error. Bu there are lots of questions and answers when I search “Failed to execute microflow for deeplink deploy, check the log for details ”
