interface conversion: interface {} is []interface {}, not map[string]interface {}

[voslartomas]

What happened?

After recent upgrade to newest gqlgen we encounter this error, it seems like it is newly generated for inputs like this

GearboxCreateLayoutInput:
    model: "map[string]interface{}"

interface conversion: interface{} is []interface{} not map[string]interface {}

It seems related to changes in 2839 or #2830

What did you expect?

Minimal graphql.schema and models to reproduce

versions

• go run github.com/99designs/gqlgen version?
• go version?

to clarify,

input GearboxCreateLayoutInput {
  abc: String
  tiles: [GearboxLayoutTileInput]!
}

input GearboxLayoutTileInput {
  x: Int
  y: Int
}

GearboxCreateLayoutInput:
    model: "map[string]interface{}"
GearboxLayoutTileInput:
    model: "map[string]interface{}"

The tiles field ends up assumed as a map[string]interface{} instead of a []interface{}

case "tiles":
	ctx := graphql.WithPathContext(ctx, graphql.NewPathWithField("tiles"))
	data, err := ec.unmarshalNGearboxLayoutTileInput2mapᚄ(ctx, v)
	if err != nil {
		return it, err
	}
	if err = ec.resolvers.GearboxLayoutInput().Tiles(ctx, &it, data); err != nil {
		return it, err
	}

imo there should be a type switch when dealing with an interface instead

@endSly Hello, sorry to tag you in, but you might know if this issue is not tight to work you have done maybe?

It was after all bug in our application.
