EntityTable update and create fluentvalidation errors not show

[Jc]

Hello, when creating or updating a record, the fluentvalidation errors are not shown, I made a modification to the ApiHelper both methods, to obtain those errors and show them, they consider that the change is correct

catch (ApiException ex)
{
if (ex.Result.Errors is not null)
{
customValidation?.DisplayErrors(ex.Result.Errors);
foreach (var item in ex.Result.Errors)
{
snackbar.Add(item.Value.FirstOrDefault(), Severity.Error);
}
}
else
{
snackbar.Add("Something went wrong!", Severity.Error);
}
}

thanks I wait for the answer
