Sanic app name 'catl-battery-module' not found

I create a sanic app named “catl-battery-module”
however it can not be found in sanic.


I also use webSever=Sanic.get_app(“catl-battery-module”)
Is this probelm due to this?

Sounds like it is likely an ordering issue. Your Sanic.get_app is before the instance was created.
