yii2 Error of dynamic client validation URL - Cannot read property 'test' of undefined

wish of those help That is because you need to provide the pattern against which it would validate the URL, as you are calling the validation.url the complete options that you should pass
code :
{
    "pattern": /^(http|https):\/\/(([A-Z0-9][A-Z0-9_-]*)(\.[A-Z0-9][A-Z0-9_-]*)+)(?::\d{1,5})?(?:$|[?\/#])/i,
    "message": "Name must be a url.",
    "enableIDN": false,
    "skipOnEmpty": 1
}
function validateDynamicField() {
    $('#my-form').yiiActiveForm('add', {
        id: 'link',
        name: 'link',
        container: '.field-link',
        input: '#link',
        error: '.help-block',
        enableAjaxValidation: true,
        validate:  function (attribute, value, messages, deferred, $form) {
            yii.validation.required(value, messages, {
                "message": "Name be blank bug."
            });
            yii.validation.url(value, messages, {
                "pattern": /^(http|https):\/\/(([A-Z0-9][A-Z0-9_-]*)(\.[A-Z0-9][A-Z0-9_-]*)+)(?::\d{1,5})?(?:$|[?\/#])/i,
                "message": "Name must be a url.",
                "enableIDN": false,
                "skipOnEmpty": 1
            });
        }
    });
}

Client side validation return "Uncaught TypeError: Cannot read property 'presence' of undefined"

it helps some times For me, the second error you describe in the comments, i.e. Uncaught TypeError: Cannot read property 'first_user[name]' of undefined was apparently caused by a transposed form ID.
There is an issue on ClientSideValidation about it here:
code :
<%= form_for(resource,
  :as => resource_name,
  :validate => true,
  :html => { id: 'user_new' },
  :url => registration_path(resource_name)) do |f| %>

I wish this help you I found the solution: use renderAjax() instead of renderPartial() when echoing out the view.

will help you Since you are making a asynchronous request, initially results will be undefined, use a safe navigation operator to check if the results exists and then access the data
code :
<div *ngFor="let result of results?.data">
      {{ result | json }}
 </div>

it fixes the issue I am currently trying to use SignalR in a .NET web app. After reviewing numerous posts/articles, I'm still stumped. On page load, I am receiving an error: , I think you missed to add the autogenerated SignalR Hub Script
code :
<script src="signalr/hubs"></script>
<script src="somedomainorinstance/signalr/hubs"></script>
$.connection.hub.url = url + "/signalr/hubs";
$.connection.hub.logging = true;
$.connection.hub.start()
    .done(function () { console.log("Signal R connected"); })
    .fail(function () { console.log("Could not Connect to signal R hub!"); });

//I added this to established the connection again in case of a disconnect
$.connection.hub.disconnected(function () {
    setTimeout(function () {
        $.connection.hub.start();
    }, 5000); // Re-start connection after 5 seconds
});

//put the rest of your code here

will help you It looks like you're not setting your member variable, or you're using the incorrect variable to reference the user running the command.
You can either set the member variable to the member calling the command, but since you're only using it once, it's better to simply use it directly.
code :
...
if (msg.content.startsWith("&kick")) 
      {
        // Get the member calling the command.
        if(msg.member.hasPermission("ADMINISTRATOR"))
...
