ansible varibals do not passing to roles that in include_role

[Meir Yanovich]

i have this ansible structure its part of large codebase :

it seems that when running the main playbook the defaults/main.yml app_type:game 

don't pass on to the current_version.yml and give error 

why it doesn't use the default var in defaults/main.yml

also when i pass the same variable name from --extra-vars it gives me the same error   

when i print the variable from tasks/main.yml   

it prints the right value   

what is wrong with the include_role?

            current_version.yml
