Patch error handling key conflict

[___Pool___]

Is there a way to catch a key conflict error rised by dataverse in order to present a user friendly error to the user instead of the long technical generic message of key conflicts?

I have an entity E on Dataverse with a key constraint composed by 2 fields A,B. Currently when I patch a record in E if dataverse incurs in a key conflict it raises an excelption causing a long technical message to be prompted to the user.

I would like to catch this error in order to prompt a more user friendly message to our user.

With this in mind I wrote the following snippet of code:

Patch(E,myRecord,{A:"myValueA",B:"myValueB"});
If(
     IsEmpty(
        Errors(
           E,
           myRecord
       ),//doStuff

       Notify("My User friendly message",Error)
)

how can I handle the exception rised by the Patch formula in order to grab the message and substitute it with a more user friendly message?

I implemented a workaround: for not incurring in the key conflict error I am fatching the record before patching it

UpdateContext(
{
      recordAlreadyExists: CountIf(
          E,
     A=myrecord.A && B=myRecrod.B
) = 0
}
);

then I am patching the update just in case the variable recordAlreadyExists is false.

Let me know if you can find another way to accomplish this
