This is the working solution which worked for me fine
onChange catalog client script on Attachment type variable
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
g_form.hideFieldMsg('variableName');
var ga = new GlideAjax('ValidateAttachmentFileName');
ga.addParam('sysparm_name', 'checkFileName');
ga.addParam('sysparam_attSysId', newValue);
ga.getXMLAnswer(function(answer) {
if (answer.toString() == 'invalid') {
g_form.showFieldMsg('variableName', 'Invalid file name', 'error');
}
});
}Script Include: It should be client callable
var ValidateAttachmentFileName = Class.create();
ValidateAttachmentFileName.prototype = Object.extendsObject(AbstractAjaxProcessor, {
checkFileName: function() {
var badChars = /[%$@()&<>'"]/;
var sysId = this.getParameter('sysparam_attSysId');
var gr = new GlideRecord("sys_attachment");
gr.addQuery("sys_id", sysId);
gr.query();
if (gr.next()) {
if (badChars.test(gr.file_name.toString()))
return 'invalid';
else
return 'valid';
}
},
type: 'ValidateAttachmentFileName'
});Output: Working fine

I used the same solution which you shared here, please check the below screenshot.
FYI, I also used 'allowed_extensions=csv' variable attribute for this variable.
Client Script (Customer Service Application Scope)
Script Include:
At first I tried with the same scope (customer service) for both scripts, it gave me the same error so I just created a script include in global to check but unfortunately I got the same error.
I am getting the below two errors when I created script include in customer service:
