How to show custom error message without error code

[manosingh]

I use the function " throw new BadRequest('my error message');

But this one throws error along with the error code "Error:400".

How i can remove the Error:400 from it or is there any other function to throw custom error without error code.

Please help me on this , Thanks in advance

Hello,
maybe :
you return a value : myError=true

and then on client side :

Espo.Ui.notify('MyError', 'error', 2000);

Simple for me

Hi Thanks for the response , but i didnt get you clearly

In my controller function i try to check a conditional throw error

public function actionDelete($params, $data, $request) {
try {

if($result_number_column['count(*)'] > 0)
{
throw new BadRequest('schedule which has delivery form cannot be deleted');
}

} catch (Exception $ex) {
throw new Error("Error while delete a proposal.");
}
return parent::actionDelete($params, $data, $request);
}

I get an error alert like this please find the attachment. in that alert i need to remove "Error:400"
