I added dialyxir in my umbrella application root .its rc version

          {:dialyxir, "~> 1.0.0-rc.4", only: [:dev], runtime: false}

And in my project list i added plt like this:

      dialyzer: [plt_add_deps: :transitive]

When I run mix dialyzer . It gives me lots and lots of warnings about unknown functions and plugs and other stuff:

These are the few from the complete log.

There are errors about callback missing. What does it expect for a callback?

I tried changing dialyzer: [plt_add_deps: :project]. But nothing seems to be working.

Any helps suggestions will be much appreciated.

Thanks
