下面的代碼為 生成以下 TypeScript 錯誤：response.accessTokenTS2339：屬性“accessToken”在類型“void |上不存在TokenResponse'.import * as Msal from '@azure/msal-browser'export async function getTokenPopup(request: Msal.TokenExchangeParameters) {  return await auth.acquireTokenSilent(request).catch(async () => {    return await auth.acquireTokenPopup(request).catch((error) => {      console.log('login with popup failed: ', error)    })  })}const getGraphDetails = async (  uri: string,  scopes: Msal.TokenExchangeParameters,  axiosConfig?: AxiosRequestConfig) => {  return getTokenPopup(scopes).then((response) => {      return callGraph(uri, response.accessToken, axiosConfig)  })}當檢查 TokenResponse 的 TS 定義時，它清楚地表明該屬性在對象上可用：accessTokenexport type TokenResponse = AuthResponse & {    uniqueId: string;    tenantId: string;    scopes: Array<string>;    tokenType: string;    idToken: string;    idTokenClaims: StringDict;    accessToken: string;    refreshToken: string;    expiresOn: Date;    account: Account;};我做錯了什么？
