How to use the yaml-ast-parser.load function in yaml-ast-parser

export default function parseYamlAST(ymlPath) {
  try {
    const contents = fs.readFileSync(ymlPath, 'utf8')
    lineNumbers = [] // reset current AST line Numbers array
    window.CURRENT_AST = {} // reset current AST
    window.CURRENT_AST.PATH = ymlPath
    lineNumbers = getLineNumberInfo(contents)
    // console.log('lineNumbers', lineNumbers)

    const yamlAST = yaml.load(contents)
    const nullYamlValues = []
    const valueWithParent = []
    parseAST(yamlAST, valueWithParent, nullYamlValues)
    // console.log('nullYamlValues', nullYamlValues)
    // console.log('valueWithParent', valueWithParent)
    // console.log(window.CURRENT_AST)

    // TODO: Validate Yaml Fields
    // validateYamlFields(valueWithParent)
    return yamlAST
  } catch (e) {
    return e
  }
}
