IfError not working with Patch

[SabineR]

Hello,

I have 2 questions about the feature IfError():
1st one: can you confirm that, even it's still an experimental feature,  IfError() won't be deprecated in the future, but it's still an experimental feature as you are working on its improvement? 

2nd one: I try to implement it when inserting/updating a Sharepoint list with Patch().
I tried to test it by Patching a new item with one required field empty, but it failed:
the IfError() doesn't work and the item is registered in the list with the mandatory field empty.

Is there any additional configuration we must do on the Sharepoint list?

The code is basic:

IfError(Patch(table1,Defaults(table1),{....})

    , [...sending email with error detail...]

    ) 

Many thanks in advance for your help,

Hi @SabineR 

Here is the same one for Error handling

Patch(
     'Test Scores',
     Defaults('Test Scores'),
     {
         TestName: txt_TestName.Text
     }
 );
 If(
     !IsEmpty(Errors('Test Scores')),
     Notify(
         Concat(Errors('Test Scores'), Column&": "&Message),
         NotificationType.Error
     ),
     Navigate('Success Screen');
 )

 Note: You can update yours. Instead of notification, we can send an email.

Hi @SabineR 

Sending email if any error

Patch(
     'DataSource',
     Defaults('DataSource'),
     {
         TestName: "Test"
     }
 );
 If(
     !IsEmpty(Errors('DataSource')),
    Office365Outlook.SendEmailV2(
        "EmailId",
        "Error has Occured",
        Concat(Errors('DataSource'), Column&": "&Message),
        {Importance: "High"}
    ),
     Navigate('OtherScreen');
 )

Note: Make sure to add Office365Outlook as Data source

Hi @StalinPonnusamy , thank you for your 2 messages. 

As the 2 solutions, IfError() and Errors(), exist, is Errors() the more appropriate for Error handlings from Sharepoint?

Kind regards,

Sabine

Hi @SabineR 

Possible to get multiple errors. So we concatenate the errors and display them. This should work for a single error as well. So better to handle multiple whenever possible.
