Custom Error message not displayed in power app

(0) ShareShare
ReportReport
Posted on by Flyingfishnm 111

Hi

I'm trying to display a custom error message if a Patch() fails. It's not displaying my text but just the standard message. Please see my code below. I have turned on formula error processing in setting for the app. Any clues? 

Thanks for any insights 😊

 

If(

    nErrorCount < 1,

    Patch(

        'DocuLibrary',

        LookUp(

            'DocuLibrary',

            ID = glbSelectedDocID

        ),

        {

            'Sign Off Status': "In Progress",

            ExpectedApprovalCount: nApproverCnt,

            ApprovalRequester: CompUser.Email,

            'Approved by Date': DateValue(dteApprovedByDatePicker.SelectedDate)

        }

    );

    //if it fails display error, try again

    If(

        !IsEmpty(Errors('DocuLibrary')),

        Set(Msg0, $"{First(Errors('DocuLibrary')).Message}");

        Notify(

            Concat(

                Errors('DocuLibrary'),

                Msg0 & " - Failed to update document for workflow, please try again."

            ),

            NotificationType.Error

        );

, //else, update approval history list

      ….stuff here…..

); //end of update code

    Hi @Flyingfishnm ,

     

    Please try this:
    1\ Use

    If(

 nErrorCount < 1,

 Patch(

 'DocuLibrary',

 LookUp(

 'DocuLibrary',

 ID = glbSelectedDocID

 ),

 {

 'Sign Off Status': "In Progress",

 ExpectedApprovalCount: nApproverCnt,

 ApprovalRequester: CompUser.Email,

 'Approved by Date': DateValue(dteApprovedByDatePicker.SelectedDate)

 }

 );

 //if it fails display error, try again

 If(

 IsEmpty(Errors('DocuLibrary')),

 

 // update approval history list

 ….stuff here…..

); //end of update code

     

    Besides, set the onError property of app to:

    Set(Msg0,$"{First(Errors('DocuLibrary')).Message}");Error(Concat(Errors('DocuLibrary'),Msg0&" - Failed to update document for workflow, please try again."))

     

    Best Regards,
