Typescript generated client type error with slice optional query parameters

[PhakornKiong]

Generated a typescript client that have optional query parameters that is slice of string.

encore gen client -e local -l typescript > ./client.ts

type queryParameters struct {
	Name []string `query:"id" encore:"optional"`
}

func World(ctx context.Context, query queryParameters) (*Response, error) {
	rlog.Debug("hello world", "query", query)
	msg := "Hello, " + "!"
	return &Response{Message: msg}, nil
}

result in

export interface queryParameters {
        Name?: string[]
    }

const query = makeRecord<string, string | string[]>({
      id: params.Name.map((v) => v),
  })

and IDE is complaining that params.Name might be undefined.

Probably can be fixed by optional chaining?
