Hi Lori

At what point is this mysterious error thrown?

Eg opening a content item that has the Block List Editor on

or when opening the Block List Editor to choose a block

or are you rendering the blocks 'inline' like Nested Content

or is it displayed when you choose a type of block and are about to enter data?

Does the ElementType that describes your Block List Editor block contain a Media Picker?

and if so does that Media Picker have a configured 'start node'?

The error looks like a bug - it's basically not able to get the id of a media item in order to check whether the current user has permissions to view/pick it... but that seems bizarre, and so the answers to the above may give a clue as to where to start looking

Hi Mark Literally, go to add the block to the block list it throws this error. The block contains two media pickers, two textboxes nothing overly major. It renders fine other than this error popping up.

I try add a start node to the media picker

Live editing mode is enabled.

When the images are set doesnt seem to happen

Hi Lori

Yes, so it seems when an image is not set, there is a check being requested to see if the current user has access to that image 'or not'.

I've just installed a fresh copy of Umbraco 8.12.2

And set up your scenario, just to see if I can see something going wrong.

But I can't make it happen.

But I am logged in as an Admin, and don't have any start node restrictions - what is your scenario?

Also which version of Umbraco are you using?

Also did you update the Element Type, after creating some of the blocks initially? - eg does deleting all the blocks, saving, and reloading the backoffice page, mean that new blocks do not trigger the issue..

Finally, do you have a custom view with the block? and is that trying to get the image back from the picker, and so is trying to do so when an image isn't picked?

Hi I am logged in as an admin. Using Umbrao version 8.11.1

Followed the https://our.umbraco.com/documentation/getting-started/backoffice/property-editors/built-in-property-editors/Block-List-Editor/

Have just created a brand new block but the issue remains. I actually moved the images out to the settings - as this is possible a better location for them long term. I do a null check in the controller.

I do have a custom view.

My Controller

 $scope.fontColor = $scope.block.settingsData.fontColor

    if ($scope.block.settingsData.image != null) {
        mediaResource.getById($scope.block.settingsData.image)
            .then(function (media) {
                $scope.imageUrl = media.mediaLink;
            });
    }

    if ($scope.block.settingsData.backgroundImage != null) {
        mediaResource.getById($scope.block.settingsData.backgroundImage)
            .then(function (media) {
                $scope.bgImageUrl = media.mediaLink;
            });
    }

    if ($scope.block.settingsData.curve != null) {
        mediaResource.getById($scope.block.settingsData.curve)
            .then(function (media) {
                $scope.CurveImageUrl = media.mediaLink;
            });
    }

My View

<div ng-controller="headerNewController" ng-click="block.edit()">




    <table cellpadding="4">
        <tr>
            <td style="width:50%; background-image:url('{{bgImageUrl}}'); background-size:cover; background-repeat:no-repeat;">
                <h2 ng-bind="block.data.title"></h2>
                <p ng-bind-html="block.data.paragraph" style="color:{{fontColor}}"></p>
            </td>     
            <td style="width:50%; background-image:url('{{imageUrl}}'); background-size:cover; background-repeat:no-repeat;">
                &nbsp;
            </td>
        </tr>
    </table>








</div>

Hi Lori

Ahh, I think that makes more sense, I think it's the getById of the MediaResource that will trigger the check to see if the current user has permissions to access that id. (you could comment it out temporarily to confirm)

My guess here is that perhaps $scope.block.settingsData.backgroundImage isn't null, but is instead 0 or an empty string ? when an image isn't picked?

You could use console.log() to see what the value is when the null check is being made, I did something recently in a custom block list editor view for a content picker:

http://tooorangey.co.uk/posts/editing-some-tabular-data-in-umbraco-v8/

and it looks like I ended up checking the 'length' of the value rather than trying to detect if it was null...

eg

if ($scope.block.settingsData.image.length > 0) {

so that might be worth a shout...

Marc

Marc thank you so much for sticking with me - that was it

scope.block.settingsData.backgroundImage.length > 0

rather than null

is working on a reply...
