type Query {
    id: Int!
}

type Mutation {
    userCreate: UserCreatePayload!

The error occurs because after executing the bindField function, in the case of a Query, f.TypeReference becomes nil.

gqlgen/codegen/field.go

Lines 69 to 75 in d6270e4

	if err = b.bindField(obj, &f); err != nil {
	f.IsResolver = true
	if errors.Is(err, config.ErrTypeNotFound) {
	return nil, err
	}
	log.Println(err.Error())
	}

The reason f.TypeReference becomes nil is because Query cannot be found in b.cfg.Models.

gqlgen/codegen/config/binder.go

Lines 381 to 383 in d6270e4

	if len(b.cfg.Models[schemaType.Name()].Model) == 0 {
	return nil, fmt.Errorf("%s was not found", schemaType.Name())
	}

The reason Query cannot be found in b.cfg.Models is likely because it is being excluded as shown below.
However, simply modifying this code to not exclude Query will result in many errors.

gqlgen/plugin/modelgen/models.go

Lines 135 to 137 in d6270e4

	if schemaType == cfg.Schema.Query || schemaType == cfg.Schema.Mutation || schemaType == cfg.Schema.Subscription {
	continue
	}

What did you expect?

generate success.
