AFAIK, Replace the invalid icon value at line 34 with a valid icon name like "user" or "home". fn!getfontawesomefriendlynamebyid_appian_internal() is the internal function. Can you share code snippet for same(If this does not work)?

I encountered this issue after rearranging the page menus in the Application's Site configuration. I was able to resolve the issue this way: 
 
 Edit each menu item for pages that were generated by Appian Composer
 
 Select a glyph icon (they will be empty) 
 Scroll to the bottom and set Visibility to "Always Show" instead of "Only show when..." since the expression is empty 
 [Done]
