abp properties undefined except for abp (JavaScript) #9184

SBJ created 4 years ago

Hi,

The version used is 8.7.0.

We're currently trying to extend the chat functionality with a custom SignalR hub. Hoever, my colleague and I came across a very weird issue also illustrated in this thread: https://support.aspnetzero.com/QA/Questions/9080/Javascript-Error The difference being that we didn't manage to encounter any exception using Postman, yet all properties of global variable abp cannot be found. The two properties we're trying to access are abp.services.app and abp.signalr.

I've attached a screenshot to illustrate how logging the abp to the console inside my partial view displays all the available and filled properties. But then, the next line of code (so no in-between tampering or mutation), it says it cannot call startConnection() because abp.signalr is undefined all of a sudden.

The startConnection() method call is executed as such and we've mapped the hub in Startup.cs.

<script type="text/javascript">
    var registrationChatHub = null;
    var abp = abp;
    console.log('ABP contents:', abp);

    abp.signalr.startConnection(abp.appPath + 'signalr-chat-registration', function (connection) {
        registrationChatHub = connection; // save reference

        connection.on('getMessage', function (message) {
            console.log('received msg:', message);
        });
    }).then(function (connection) {
        abp.log.debug('Connected to RegistrationHub server.');
        abp.event.trigger('registrationHub.connected');
    });

    abp.event.on('registrationHub.connected', function () {
        registrationChatHub.invoke('sendMessage', 'Hello!');
    });
</script>

Any help would be greatly appreciated.
