ast.Merge error cannot merge Mapping into Anchor

[rjshrjndrn]

Hi,

First of all, thank you for this amazing library.

I'm trying to merge 2 yamls, and getting error cannot merge Mapping into Anchor. I tried to search in the docs, and in repo to be in vein.

I'm getting started with golang. So can't crack very deep things 😬

Appreciate any help.

Code

package main

import (
	"fmt"
	"strings"

	"github.com/goccy/go-yaml"
	"github.com/goccy/go-yaml/parser"
)

func main() {
	original := `
chalice: &chalice
  env:
    environment: dev
    cloud: AWS
  other:
    - hey
    - hello
global:
  chalice: *chalice
	`
	override := `
chalice: &chalice
  env:
    environment: production
    jwt_enabled: false
global:
  chalice: *chalice
	`
	orig, err := parser.ParseBytes([]byte(original), 0)
	if err != nil {
		fmt.Println("panic")
		panic(err)
	}

	path, err := yaml.PathString("$.chalice")
	if err != nil {
		panic(err)
	}
	err = path.MergeFromReader(orig, strings.NewReader(override))
	if err != nil {
		panic(err)
	}
}

error
