Error during learning path: Create an App with Advanced Page Building 3.7.2 Creating a Custom Navigation Layout

Hi all   Does someone else gets the following error? I’ve restarted building the app following the learning path twice to see if the error occurs again.  The errors pops up when I’m adding the snippet call to the header in creating a new layout.    Any tips how to proceed?

Hello, sometimes this occurs. If you have time to respond with brief summary of what you were doing when the error popped up, it could help the engineers fix whatever is causing it. Otherwise, close out the error and keep working on the steps in the learning path as best you can. 

Note: There some snippet fixes in Mendix 8.10 so maybe the problem went away after 8.9 (the version you may have been using when posting this question).
