    nucache 500 error after deploy

    We have site running on v8.1.1 and every now and then after a deploy (using azure devops) we get the following error:

    System.IndexOutOfRangeException: Index points outside the properties array, which means the properties array is corrupt.
    

    at Umbraco.Web.PublishedCache.NuCache.PublishedContent.GetProperty(String alias) in d:\a\1\s\src\Umbraco.Web\PublishedCache\NuCache\PublishedContent.cs:line 317

    We have to recycle app pool then it site fires up.

    In the Umbraco source we have:

    if (index >= PropertiesArray.Length) // should never happen - properties array must be in sync with property type
                throw new IndexOutOfRangeException("Index points outside the properties array, which means the properties array is corrupt.");
    

    Anyone seen this before?

    Regards

    Ismail

    Hi

    Can't tell at the moment if this is an uSync issue or something within the Umbraco Core... we have an issue here

    https://github.com/KevinJump/uSync8/issues/40

    we are going to see what we can reproduce/figure out.

    Just to update,

    Have upgraded to latest version of usync but still get same issue. The error seems to occur in one of our components where we have the following line:

    using (var contextReference = _context.EnsureUmbracoContext())

    I am guessing that is then getting at nucache?

    Hi,

    we have pushed v8.2.2 release of uSync out, hopefully with some mitigation of this issue

    https://github.com/KevinJump/uSync8/releases/tag/8.2.2

    the main thing is asking nucache to rebuild at the end of an import,

    but we've also tried to reduce the number of times we hit an item save because it appears they cause cache rebuilds even if the underlying item hasn't changed, so this should reduce the number of times we cause a cache rebuilt to occur.

    feedback on this most welcome.
