Minimal graphql.schema and models to reproduce

type Query {
  countries: [Country!]!
}

type Mutation {
  createCountry(input: CountryCreateInput!): Country
}

# input
input CountryCreateInput {
  name: String!
  code: String!
}

scalar DateTime
scalar Json

type Country {
  name: String!
  code: String!
  images: [Json!]!
  createdAt: DateTime!
}

https://github.com/99designs/gqlgen/releases/tag/v0.8.0 ?

I'm experienced same issue, but with usual types, for example Country from example above. Used dep to add that dependency and yes it is v0.8.0
My schema is more complex and it fails randomly at different types. v0.7.2 works great with the same exact schema.

[DBL-Lee]

Adding the custom scalar type in gqlgen.yml models fixed the problem for me.

[thanhngvpt]

thank you.

[Dispersia]

Why did you close this? This is still an issue that needs to be fixed - it just has a workaround. The same schema in 0.7 doesn't work in 0.8

[JulienBreux]

I'm ok with @Dispersia.

This is a regression. No?

[thanhngvpt]

@Dispersia Sorry, I've reopened it. It also same error with Json or (non builtin scalar type)

This sounds like a separate issue?
