I have the following code and it's always failing. What is the best way to provide a detailed error message so I can see what the issue is?
function createDataStore(){

    var url = GLOBAL_URI + '/Users';
    myNamespace.UserDataStore = new Ext.data.JsonStore({
        url: url,
        root: 'Subscriptions',
        id: 'userId',
        fields: [{
            name: 'userId'
        }, {
            name: 'userName'
        }]
    });
    
    var objUser = {
        "userId": "",
        "Id": ""
    };
    
    
    myNamespace.UserDataStore.proxy.conn.jsonData = objUser;
    myNamespace.UserDataStore.proxy.conn.method = 'POST';
    
    myNamespace.UserDataStore.load({
        callback: function(records, o, s){
            if (!s) 
                Ext.MessageBox.show({
                    title: 'Error',
                    msg: 'POST method failed',
                    buttons: Ext.MessageBox.OK,
                    icon: Ext.MessageBox.ERROR
                });
            else 
                Ext.getCmp('ddlUserId').setValue(userId);
        }
    });
}

I've debugged it using Fiddler and it is showing me a "HTTP/1.1 400 Bad Request" error.

Any thoughts on ways to solve that?

I think the error is caused by not specifying the target server side script where the data is supposed to be POSTed

try to add something like this:

myNamespace.UserDataStore.proxy.conn.url = 'file_name.php'

before or after :

    myNamespace.UserDataStore.proxy.conn.jsonData = objUser;
    myNamespace.UserDataStore.proxy.conn.method = 'POST';
