Schema could not be fetched absinthe error

I am using absinthe in the project, and I am not that well-versed with Graphql. Recently, I am getting this error in the playground and schema is not generating.

Request: POST //graphql/graphiql
** (exit) an exception was raised:
** (UndefinedFunctionError) function nil.name/0 is undefined
    nil.name()
    (absinthe 1.6.7) lib/absinthe/type/built_ins/introspection.ex:349: Absinthe.Type.BuiltIns.Introspection.render_default_value/4
    (elixir 1.10.4) lib/enum.ex:1396: Enum."-map/2-lists^map/1-0-"/2
    (elixir 1.10.4) lib/enum.ex:1396: Enum."-map/2-lists^map/1-0-"/2
    (absinthe 1.6.7) lib/absinthe/type/built_ins/introspection.ex:333: Absinthe.Type.BuiltIns.Introspection.render_default_value/4

If I run mix absinthe.schema.json --schema SupertrendsWeb.GraphQL.Schema, it gives the same thing and there isn’t much in the error to debug.
Could anyone please suggest how to debug this issue?

Based on that stacktrace, I’d guess there’s a misconfigured Enum someplace that’s crashing in render_default_value:
