Entity with custom ID through edge-schema doesn't resolve

[juliusmh]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Running go generate is not possible.

$ go generate ./ent
entc/gen: resolving edges: missing edge-field Similarity.product_id for edge schema used by Product.alternatives in Through("similarities", Similarity.Type)
exit status 1
ent/generate.go:3: running "go": exit status 1

Expected Behavior 🤔

The code should generate successfully.

Steps to Reproduce 🕹

I copied the "friendships" example in Edge Schema
part of the documentation. I added a "custom" id to the Product entity.

func (Product) Fields() []ent.Field {
	return []ent.Field{
		field.UUID("id", uuid.UUID{}).Default(uuid.New),
	}
}

func (Product) Edges() []ent.Edge {
	return []ent.Edge{
		edge.To("alternatives", Product.Product).Through("similarities", Similarity.Type),
	}
}d
func (Similarity) Fields() []ent.Field {
	return []ent.Field{
		field.UUID("a_id", uuid.UUID{}),
		field.UUID("b_id", uuid.UUID{}),
	}
}

func (Similarity) Edges() []ent.Edge {
	return []ent.Edge{
		edge.To("a", Product.Type).
			Required().
			Unique().
			Field("a_id"),
		edge.To("b", Product.Type).
			Required().
			Unique().
			Field("b_id"),
	}
}
