Remove or edite the default error message

[kerolos samir]

Hi team 
Is there any way to modify this error message in the screen 
Or remove it and show another one with a client script

Hi @kerolos samir 

The default error ( “Could not parse xxx as an integer” ) is coming from ServiceNow’s internal field type validation because your field is defined as Integer in the dictionary. That system validation always runs before/alongside your client script, and unfortunately you cannot "turn it off" for that field type.

Script Modified :

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
if (isNaN(newValue)) {
g_form.showFieldMsg('max_waiting_time',
'Maximum waiting time should be a number (in seconds).', 'error');
} else {
g_form.hideFieldMsg('max_waiting_time');
}
}

it didn't work 
what works is this 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

if (!Number(newValue) || !Number(oldValue)) {

getMessage(`Maximum waiting time should be Number ${newValue}`, function(msg) {

g_form.hideErrorBox('max_waiting_time');

g_form.showErrorBox('max_waiting_time', msg);

});

}

}
But the could not parse message appear as a flicker in the ui before the second one replaces it

Fix Options
Option 1: Direct Message (Recommended)
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') return;
    if (!Number(newValue)) {
        g_form.showErrorBox('max_waiting_time', 'Maximum waiting time must be a valid number');
    }
}

Option 2: Proper getMessage Usage
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') return;
    if (!Number(newValue)) {
        getMessage('max_waiting_time_error', function(msg) {
            g_form.showErrorBox('max_waiting_time', msg);
        });
    }
}

Then create sys_ui_message record:

Key: max_waiting_time_error
Message: Maximum waiting time must be a valid number
