Dialyzer error using GraphiQL plug

[woylie]

This also happens when adding the socket or socket_url options. No change after upgrading to Phoenix 1.5.6.

I get this as well if I just specify advanced:

# works:
    forward("/graphiql", Absinthe.Plug.GraphiQL, schema: IdoWeb.Schema)
# fails:
    forward("/graphiql", Absinthe.Plug.GraphiQL, schema: IdoWeb.Schema, interface: :advanced)

Something similar appears to have been reported to phoenix itself:

phoenixframework/phoenix#3393

I'm going to close this, since our direction forward involves removing GraphiQL from absinthe_plug itself. Please chime in if any of you know if there's an easy fix though...

I believe it can be worked around with the following annotation:

@dialyzer {:no_return, {:__checks__, 0}}
