There can be only one type named "CacheControlScope"

[stevez86]

I'm using graphql-import and ApolloServer and I'm running into the following error:

Error: There can be only one type named "CacheControlScope".

Enum value "CacheControlScope.PUBLIC" can only be defined once.

Enum value "CacheControlScope.PRIVATE" can only be defined once.

There can be only one directive named "cacheControl".

Referencing this issue: #153 I had to manually add the following to my schema:

enum CacheControlScope {
  PUBLIC
  PRIVATE
}

directive @cacheControl(
  maxAge: Int
  scope: CacheControlScope
) on OBJECT | FIELD_DEFINITION

For a period of time this was working without error until recently and I started getting the error above. It happens in both importSchema and the webpack plugin. When I print out the typeDefs on my server I see that it's only declared once. Any help on troubleshooting while I keep looking into this would be appreciated.

I'm closing this to reference the culprit, ApolloServer apollographql/apollo-server#2428

@stevez86 This seems happening to me, so what was the solution again?

Just updated to latest and the check is automatic. No need to implement anything.
