Hello,

I'm encountering an issue where my Patch function fails as expected (due to a document being open and locked by another user), but the success notification is still displayed. Here’s the code I’m using:

If(
    IsError(
        Patch(
            MyLib,
            LookUp(MyLib, ID = ThisItem.ID),
            {
                MyField: Self.Selected
            }
        )
    ),
    Notify("Error", NotificationType.Error, 3000),
    Notify("Success", NotificationType.Success, 3000)
)

It seems like IsError isn't properly capturing the error.

Does IsError not handle certain errors (like file locks) properly? What’s the correct way to manage these types of errors in Power Apps?

Thank you,

Charles

The Patch function itself doesn’t return an error flag that IsError can catch for data-related issues. It simply performs the action, and if there’s an issue (like a file lock), PowerApps doesn’t consider that an "error" for the IsError function to detect.

Use the Errors function, which is designed to detect and handle data-related issues from your data source.

Hi CharlesPP ,

Try the below code, may be that work around helps.🤞

Patch(
MyLib,
LookUp(MyLib, ID = ThisItem.ID),
{ MyField: Self.Selected }
);

If(
CountRows(Errors(MyLib)) > 0,
Notify("Error", NotificationType.Error, 3000),
Notify("Success", NotificationType.Success, 3000)
)

Also try IfError
IfError( Patch( MyLib, { ID: ThisItem.ID, MyField: Self.Selected } ), Notify("Error", NotificationType.Error, 3000), Notify("Success", NotificationType.Success, 3000) )

Thanks for your answers.

@WarrenBelz, IfError didn't detect the error, exactly like IsError.

@Nirav (Akira28) and @CU15102032-0, this solution works, but I still get the standard error notification and my own notification. Is there any way to have only my own notification?

Thank you very much!

I will bow out here - just note that IfError/IsError are designed to "suppress" system errors and replace them with something meaningful (I am surprised that neither work for you). If you do not use one of them, you will get the system error.
