HarmonyOS 将枚举转成对象，使用keyof会报错，怎么修改？

enum Color { 
  Red = 1, 
  Green = 2, 
  Blue = 3, 
} 
 
function enumToObject<T extends Record<string, string | number>>(e: T): Record<keyof T, string | number> { 
  const obj = {} as Record<keyof T, string | number>; 
  let keyList = Object.keys(e) 
  for (let i = 0; i < keyList.length; i++) { 
    const key: keyof T = keyList[i]; 
    if (Number.isNaN(Number(key))) { 
      obj[key] = e[key] 
    } 
  } 
  return obj; 
} 
const colorObj = enumToObject(Color); 
let res = colorObj.Red.toString() 
console.log(res);
