This is now a very different error.
It seems you are trying to build a GraphQL API with Absinthe?
For better help, we need to see more of the project. Maybe a Github repo?
This might even be better under a new post, as the title of the post is resolved.
But if you don’t, I suggest you take everything out and build the project slowly.
Add Ecto, get it working, then Absinthe, then etc…

You can read more about the setup in the docs

(CompileError) module Absinthe.Ecto is not loaded and could not be found. This may be happening because the module you are trying to load directly or indirectly depends on the current module
