Javascript 从commonJS函数调用调用typescript接口

我在ts AuthorityProvider中有一个代码示例，它是一个在库中实现的接口，如下所示

export interface AuthorityProvider {
     /** Get subset of `availableKeys` needed to meet authorities in `transaction` */
    getRequiredKeys: (args: AuthorityProviderArgs) => Promise<string[]>;
}

您在TS控制台中有任何错误吗？我不是在尝试TS脚本，我想将TS代码转换为commonJS

const authorityProvider: AuthorityProvider = {
  getRequiredKeys: (args: AuthorityProviderArgs): Promise<string[]> => {
    return Promise.resolve([accountPublicKey])
  },
}

const authorityProvider = ( getRequiredKeys => {  
  return Promise.resolve([accountPublicKey]) 
})
