Hello @Sowmya ,

Please try the below code in catalog client script and see how it works for you , I have tested it from my end and its working fine for me so just let me know your views on this.

onChange Client Script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }

    var forbiddenValues = ["/", "/usr", "/home", "/boot", "/boot/efi", "/dev", "/tmp", "/var", "/opt"];
    
    for (var i = 0; i < forbiddenValues.length; i++) {
        if (newValue.includes(forbiddenValues[i])) {
            var errorMessage = "Invalid value. The entered value is not allowed.";
            alert(errorMessage);
            g_form.setValue('description', '');  // Clear the 'description' field if an invalid value is entered
            return;
        }
    }
}

Please Mark ✅Correct if this solves your query and also mark 👍Helpful if you find my response worthy based on the impact.

Thanks,

Hi @Sowmya

The simplest way to do this is to make use of the  Validation Regex functionality. Define a regular expression for a variable by referring this link https://docs.servicenow.com/bundle/tokyo-servicenow-platform/page/product/service-catalog-management... and with regular expression ^(\/[^/ ]*)+\/?$

Then configure the Validation Regex for your Single Line Text as below :

Output :
