I've created several custom modules in D8 but this one is busting me. At first I thought it was because I was invoking a path of '/admin/structure/site_mgr' and created a RouteSubscriber to ensure it was added to the collection. To troubleshoot this further, I changed the path to 'foo/site_mgr', and tried combinations of adding '_admin_route: TRUE', destroying my reference to my RouteSubscriber, destroying my RouteSubscriber just to eliminate possible variables, running cache rebuild at each step. I verified my YAML passes linting.

I was testing if I can upgrade my site from D7 to D8. Post upgrade everything looks good except one hiccup. All my existing node's text format cannot be changed manually there for unchanged node's body does not show any text. If I change it manually however to full html everything works fine. My problem is I have 10000+ nodes and it's impossible for me to open each an everyone and changing the text format. How do I set text format without doing it manually?

After doing that and opened admin>structure>view this is the error i'm having troubles with:
