    Failed to retrieve children for media item -1

    I have upgraded Umbraco version from 6.1.5 to 7.1.8. It shows 'Failed to retrieve children for media item -1' when I try to add an image to WYSIWYG and media items does not loading to the right panel. Log file does not record any information about this error.

    Please help to resolve this as site is ready to go live

    Hi Madura

    Does the /App_Data/Logs file reveal further details? Anything marked with "ERROR" or "WARNING", which could be related? What steps did you take in order to do your upgrade?

    Hi Jan,

    I followed Upgrading Umbraco from V4 to V7 to do the site upgrade. Unfortunately no errors are captured in the error log :( Same error message will appear when I navigate to Media from any other tab

    Media Tab error

    Is there a way to capture all errors (any config settings)

    Thanks, Madura

    Hi Madura

    Ok that's really odd - It's sure a nice writeup made on that site. I think that it might also be a good idea if you check the official documentation about upgrading here https://our.umbraco.org/documentation/Installation/Upgrading/ - Both the version specific and the general documents can perhaps provide useful information. The link you posted seems to be very thorough and perhaps more up-to-date than the existing documentation in some areas - But it might also miss some of the things mentioned in the official documents.

    Perhaps you can find some nice tips in going from 6 to 7 here as well https://our.umbraco.org/documentation/Installation/Upgrading/v7-upgrade

    Hope this helps.

    /Jan

    Hi Jan,

    No luck for that :( Do you have any idea about the URL of the service that returns those images to front-end.

    Thanks, Madura

    Hi Madura

    Sorry to hear that - Unfortunately I don't have a clue about where the service is...

    Hi Jan,

    I checked the console and found these errors but not sure how to resolve this. It looks like URL does not pass all the required parameters. See below screen shoots.

    Err 1

    Err 2

    Thanks, Madura

    I am having the same issue with one media folder after upgrading from 6.x to 7.12.1 , Did you ever get a solution to this issue?

    Me too on an upgrade from 7.1.6 to 7.13.1.

    Error is:-

    Unhandled controller exception occurred
    AutoMapper.AutoMapperMappingException: 
    
    Mapping types:
    Media -> UserProfile
    Umbraco.Core.Models.Media -> Umbraco.Web.Models.ContentEditing.UserProfile
    
    Destination path:
    ContentItemBasic`2.Owner.Owner
    
    Source value:
    Umbraco.Core.Models.Media ---> System.NullReferenceException: Object reference not set to an instance of an object.

       --- End of inner exception stack trace ---
    

    Have ensured both the User Groups and individual Users have Media as their start node but still get this error.

    Also get this error if I try to set the MediaPicker's start node.

    If anyone finds this, we just fixed it. In our case it was due to a single corrupt file. We found it by creating a new folder and then trying to move it to the top of the tree. It would only go so far. The next folder up was called Temp in which there was a file called "File" which we couldn't open nor find a physical folder with it's ID. Moving the folder in the Media section to the Recycle Bin solved the whole issue.

    Hope this helps someone else :)

    Thanks for the lead Craig100. We had something similar happen:

    Media Folders were unable to list files in the back office. Controls using Media References were throwing a similar error.

    Tried to sort these media folders and discovered that they could not be updated / rearranged.

    Reviewed media folders in UmbracoNode Table. Noticed that the [nodeUser] property was mapped to a deleted a user in the Back Office.

    We updated the offending media nodes in the UmbracoNode Table to point to an existing back office user. This allowed AutoMapper to do its job. Umbraco stopped throwing an error on the failed user lookup.

    I'll review and submit a bug if needed. This occurred in an upgraded site that is 7.14

    Noticed a solution to a similar issue here:
