Hi,

I've upgraded my git repository to tag v1.8.2 but when I'm running the deployment admin page for example I'm getting the following error.

Does anyone have an idea what triggers this error? I don't find the issue

I've found the problem. For some reason while merging a project was lost (custom deployment step). This project is referenced in de deployment document but could not be found so this triggered the error.
