AWS - Status check fails when loading AMI created from snapshot

Question

I am facing a problem in which I have to refresh the scope value after 5 sec. Here's my controller constructor function where I initialize the value and call the timeout function to refresh the content after 5 sec.

static $inject = ['$scope', 'selectedCardAccount', 'CardService', 'ecAnimationService', '$interval', '$modal','$rootScope','$timeout','PromiseTimeout','$q','$stateParams'];
            constructor(public $scope,public selectedCardAccount, public CardService:services.CardService, public $interval:ng.IIntervalService, public $modal,public $rootScope:ng.IRootScopeService, public $timeout,public PromiseTimeout,public $q,public TrackPendingRequest,public $stateParams) {

    //setting the current value
    this.account = selectedCardAccount.account;

    //calling a serive again after five section to referesh the content
    $timeout(function(){
            //delete the current object
        delete this.account;
        //calling service to get result
                CardService.getAccountAndCardByShortName($stateParams.productShortName,$stateParams.id).then((succRess)=>{

            //setting the value
            //Error : cannot read property of account
            this.account = succRess.account;
        });
    }, 5000);
}

Error : cannot read property of account

Directive code :

module ec.directives {
        export class easein{
            /**
             * A directive is not new:ed up so we don´t specify anything on this class
             * */
            constructor(){
                var directive: ng.IDirective = {};
                directive.link = (scope:IEaseInNumberScope, element, attrs, ctrl:controllers.EaseInNumberCtrl) => {
                    ctrl.animateRemainingValue(scope);
                };
                directive.restrict = "EA";
                directive.template = "{{current | number : 2}}";
                directive.controller = 'EaseInNumberCtrl';
                directive.scope = {
                    duration: "=?",
                    startValue: "=?",
                    endValue: "="
                };

                return directive;
            }
        }
}

HTML :

<div class="row">
    <div class="col-xs-6">
        <h2 class="heading-small-bold light mar-l-1"
            ng-bind="'used_amount' | i18n"></h2>

        <h1 class="heading-big-thin-medium mar-l-1">
            <easein end-value="vm.account.usedCredit"></easein>
        </h1>
    </div>
    <div class="col-xs-6 align-r">
        <h2 class="heading-small-bold light mar-r-1"
            ng-bind="'left_to_spend' | i18n"></h2>

        <h1 class="heading-big-thin-medium mar-r-1">
            <easein start-value="vm.account.creditLimit"
                    end-value="vm.account.openToBuy"></easein>
        </h1>
    </div>
    <div class="col-xs-12 mar-t-2">
        <progressbar class="progress-bar" value="vm.loadingValue"
                     max="vm.account.creditLimit"
                     type="warning"></progressbar>
        <div class="flexible-header">
            <h2 class="heading-small-bold light"
                ng-bind="'last_transactions' | i18n"></h2>
        </div>
    </div>
</div>

if some one has any suggestion that how can I refresh the value after 5 section in constructor please help.

Solution

When you create an image from a snapshot, make sure you use the same architecture you used for the original instance/AMI. The default value in this wizard is i386, but in many cases you may want x86_64, which is the standard Amazon EC2 Linux architecture. This, together with selecting the exact AKI kernel - worked for me.

At a guess (check your console log, you might get more info) - either your AKI (kernel) or fstab (mounted volumes) differ. Check which AKI each image is launch with and see if they match. If it is your fstab trying to mount a non-existent volume, it should show up in your console log.

@cyberx86 Thanks so much, I was using the default kernel to make the image. Is the console log in the aws console or is it cli? I couldn't find a console log in the aws console.

[cyberx86]

You can usually view the console log from the AWS Console. In the EC2 tab, right click an instance, and select 'Get System Log' - of course, the instance has to have at least started booting (it is basically an output of dmesg on Linux instances).

Are you using a RedHat or CentOS AMI? There are (were) some issues with the way the network connection was managed that prevented copying EBS-based images.

[iberbeu]

is that the real error that you get? Normally you get cannot read property propName of whatever. Could you put the line number where you get this error?

succRess is returning the proper object. what i just need to assigned that to this.account

[Toretto]

Now this.account get updated but the value in view not changed. I have custom directive on view to show this value

[Sreekanth]

do you see the account property on succRess object?

[VRPF]

That is because the reference to the initial object has changed. What is the type of this.account ? Keep the initial reference and update the properties that are important.

[Toretto]

So what i have to do to update value of custom directive

[VRPF]

I updated my answer. try using angular.copy(succRess.account, this.account);.

[Toretto]

not it not working , I also tries to run $apply to update value but nothing got chqnaged

[VRPF]

what does the account look like ? is it an array or an object ?

[Toretto]

it's object with no of property like name,opentobuy and creditlimit etc

[VRPF]

Hard to say. I suggest that you edit your snippet to make it run and reproduce your issue, including html template. It will then be easier for me (us) to investigate the problem.
