We are running SDL Web 8.5 with DXA .Net 2.2 and having issues running DXA Resolver. When opening the publish dialog and clicking the button “Show items to publish” an error notification appears, referring to SDL Web 9.

When removing the Sdl.Web.DXAResolver.Resolver"(version= from resolvers in Tridion.ContentManager.Config the error message disappears, but then the DXA resolver is disabled.

Any idea how to run the DXA Resolver with SDL Web 8.5?

Edit, adding error message details:

The error in CME notifications is:

Unable to retrieve the list of publishable items for item(s) with id tcm:91-90259-64 
Could not load file or assembly Tridion.ContentManager.Publishing, Version=, Culture=neutral, PublicKeyToken=360aac4d3354074b' or one of its dependencies. The system cannot find the file specified.

Looking in EventLog on server gives a stack trace of the error:

  • I find it odd that if you are truly using SDL Web 8.5 you get an error referring to SDL Web 9. I would double check your setup to confirm the versions you are working on and to ensure that the versions on the different parts of the system are compatible with each-other. Jan 31, 2020 at 21:33
  • What is the exact error you get (also check the Windows event logs)? Feb 3, 2020 at 15:41
  • Thaks for responses. We are looking into the setup and configurations without any luck so far. I do not see “who” is referring to SDL Web 9. I have added error details in the question. Feb 5, 2020 at 13:43

It seems that the DXA 2.2 resolver is built against SDL Tridion Sites 9.0 API, so it can’t be loaded on a SDL Web 8.5 system.

Frankly, I’m flabbergasted, because I’m quite sure that DXA 2.2 has been tested against SDL Web 8.5.

This should be reported as a DXA 2.2 defect.

It should be possible to work around this issue by putting assembly binding redirects in your machine.config. You can find examples of such assembly binding redirects here: https://github.com/sdl/dxa-web-application-dotnet/blob/master/Site/Web.config
