Error handling inside PowerApps (Try-Catch)

[vecerpa]

My idea come with error message that is being thrown when trying to get manager of user via Office365 Users connector. More details here - https://powerusers.microsoft.com/t5/General-Discussion/Office-365-Users-ManagerV2-Error/m-p/119173.

As this is expected error that will be delivered by this connector it will be nice to have some option inside PowerApps to catch it and instead of displaying this for user of PA as "nothing to say" message, to diplay something like no manager found and this can lead to some other actions ...

After many attempts testing different controls, i have found below formula to be successful for me and is no longer spitting out the error if a user(that has no manager) uses the app.

I have tried IfError, IsBlank Not(IsBlank) and all these failed.

The only one that is working for me is IsEmpty.

If(IsEmpty(Office365Users.Manager(_myProfile.Id)), Set(_defaultApprover, Blank()), Set(_defaultApprover, Office365Users.Manager(_myProfile.Id)))

I created a label to display the information of _defaultApprover to show as "No Manager" when _defaultApprover is blank and it does show it as expected and of course users with manager will display their manager name on it.

Yeah everything that worked for me before must have been cached or something because nothing is working for me today.  So frustrating thought I had it working.  Just getting errors.  I will try your idea@isri_zainal

Nothing is working for me today that was working previously. Back to square one. So frustrating.  Come on Microsoft this is obvious stuff.

Hello All,
I've had it working using this.

I set up a couple of On Load variables:

//Define the request
Set(
    varRequester,
    Text(Office365Users.MyProfileV2().mail)
);
//Define the Manager, and use 'Alternate.Email@msflow.com' if no manager
Set(
    varApprover,
    IfError(
        Office365Users.ManagerV2(varRequester).mail,
        "Alternate.Email@msflow.com",
        Office365Users.ManagerV2(varRequester).mail
    )
)

The IfError function is new and experimental, so I had to switch on 'Formula-level error management':

Thanks

I have a custom connector that returns 400 HTTP Error statuses. When calling the connector in my PowerApp it comes to an exception, execution is aborted and I am not able to access the HTTP response. Actually, HTTP Errors should not be handled as exceptions but like expected responses. Using a switch statement I then could react based upon the HTTP status.

Same here, I need to be able to handle 4xx HTTP codes being returned when a call to a REST API, using a custom connector, fails. Instead a less-than-useful error message is displayed on the screen. Please implement a try-catch functionality.

Any news with this topic?

[RegionVarmland]

Bumping this any news? 

[david_atherton]

Why is this not sorted..... there must be a better way to handle if someone doesn't have a manager within and org browser as it'll happen.

⚠ Don't panic !

Simple Enable this:
Go to
«Experimental features» section -> Enable «Formula-level error management»

and Use this Formula: IfError(Office365Users.ManagerV2(User().Email).displayName,"");

Was glad to help 😊
