    uSync throws exception on deleting content from Backoffice

    Everytime we try and delete something from the Backoffice, uSync throws an NullReferenceException at us, and I have no idea what is causing this. Is anyone experiencing the same behaviour?

    Exception
    System.NullReferenceException: Object reference not set to an instance of an object.

    Hi

    We do have this issue that was fixed in 8.6.3 - https://github.com/KevinJump/uSync8/issues/108 it might well be this.

    https://github.com/KevinJump/uSync8/releases/tag/v8.6.3

    Does this also apply to uSync.Complete?

    I'm having the same issue that issue 108 mentions but I'm not 100% of the upgrade process if not using NuGet.

    Thank you.

    Hi Brian

    Yes that fix is in the latest version of uSync.Complete.

    if you are not using nuget, then you can upgrade by installing the latest package file from our

    (https://our.umbraco.com/packages/developer-tools/usynccomplete/)

    this should update all the required files.

    and to be sure that things like javascript are not cached - you should increment the version value inside the clientdependency.config file.

    Thank you, Kevin.

    The update worked exactly as described above and the issue is no longer present.

    Take care!
