Exception handling in power apps for runtime exceptions

Question

Basic app layout:
I created a sample power app where I just took around 20 text inputs collecting the data from it and sending it to the power automate flow (I am not using data card and form).

Now, I handled the exceptions in the power automate flow as any flow functionality got failed we should get a custom message in power apps; it is successfully working.

But, I am looking for something like,

• what if the power app didn't get any response because of timeout.(2 min is the timeout limit for "respond to the power app or flow" action.)?
• what if the power automate flow is turned off?
• what if the internet connection is broken while operating the app?
• what if the flow abruptly failed/canceled?

How could I handle these runtime exceptions?

Basically you can implement error handling on two levels:

1. Wrapping your logic in IfError() function to handle a specific error (see Shane's tutorial)
2. Define general error handling in the App.OnError property (another explanation by Shane)

To tackle broken connections, check out the Connection() function.
