I am very new to Elixir and Phoenix world and I am so sorry did not get the question.
Please guide how can I check in my environment and I am happy to provide information.

What Ben recommended to you is not Elixir-specific. It’s a Linux command.
Delete your _build and deps directories (at the root of your project) and then execute this:
mix do deps.get, compile

Oh, got it. I will try it later as I am not confident on my Elixir and Phoenix skills yet. App was developed and I am enhance it, hesitant to modify large piece of of the app at this time.
Thank you much for the help, awesome forum!

After upgrading Erlang to 21.2.4 and Elixir to 1.7.4 (from 1.6.6), I got compilation errors. Versions before:
* absinthe 1.3.2 (Hex package) (mix)
locked at 1.3.2 (absinthe) 1d16ee5c
* absinthe_plug 1.3.1 (Hex package) (mix)
locked at 1.3.1 (absinthe_plug) e97c9faa
* absinthe_ecto 0.1.2 (https://github.com/absinthe-graphql/absinthe_ecto.git) (mix)
Versions after (mix.exs):
{:absinthe, "~> 1.4"},
{:absinthe_plug, "~> 1.4"},
{:absinthe_ecto, "~> 0.1.3"},
…and in mix.lock:
* absinthe 1.4.13 (Hex package) (mix)
locked at 1.4.13 (absinthe) 81eb2ff4
* absinthe_plug 1.4.6 (Hex package) (mix)
locked at 1.4.6 (absinthe_plug) ac5d2d3d
* absinthe_ecto 0.1.3 (Hex package) (mix)
locked at 0.1.3 (absinthe_ecto) 420b6812
…I can confirm the project compiles and works under Elixir 1.7.4.

My bad. This is with Elixir 1.7.4.
Versions:
$ grep absinthe mix.lock
"absinthe": {:hex, :absinthe, "1.3.2", "1d16ee5ceeb8b90e37f936b924caacc099b9da667e9c7e6a4d729f41197123d4", [:mix], [], "hexpm"},
"absinthe_ecto": {:git, "https://github.com/absinthe-graphql/absinthe_ecto.git", "6c199e4e06568446e2de2e5731b74e2e388c94a1", []},
"absinthe_plug": {:hex, :absinthe_plug, "1.3.1", "e97c9faa6a2e29be181205d994c3ca2e2c5c5dec38aea69fcd324407f6c163c6", [:mix], [{:absinthe, "~> 1.3.0", [hex: :absinthe, repo: "hexpm", optional: false]}, {:plug, "~> 1.3.2 or ~> 1.4", [hex: :plug, repo: "hexpm", optional: false]}], "hexpm"},
I removed the path and module name. Compilation error:
== Compilation error in file lib/.../schema.ex ==
** (Absinthe.Schema.Error) Invalid schema:
Elixir.<...>.Schema:0: The root query type must be implemented and be a of type Object
#Example
defmodule MyApp.Schema do

#Fields go here
end
end
--------------------------------------
From the graqhql schema specifiation
A GraphQL schema includes types, indicating where query and mutation
operations start. This provides the initial entry points into the type system.
The query type must always be provided, and is an Object base type. The
mutation type is optional; if it is null, that means the system does not
support mutations. If it is provided, it must be an object base type.

I’ll poke you in private.
No, full recompilation with cleaning up the directories beforehand doesn’t help. That’s why I took a while – tried it several times.

Oh you’re actually on Absinthe 1.3.2? That simply won’t work on 1.7.4. Elixir changed some details about how module attributes worked that absinthe was accidentally relying on. You need to upgrade to 1.4.13.

That’s why I posted above. Just wanted to add one more voice to the fact that Elixir 1.7.4 and Absinthe 1.3 combo leads to compilation errors. And that upgrading to 1.4 fixes it.
