Description

So I am trying to update my tokens whenever they expire (Both access tokens and refresh tokens) However, It seems my token cache is always empty even this method: "acquireTokenByRefreshToken" returns a successfull response with new accessTokens. The token cache is always empty.

Error Message

tokenCache {"Account":{},"IdToken":{},"AccessToken":{},"RefreshToken":{},"AppMetadata":{}}

// Function to refresh access token using refresh token

      return myRefreshToken;

    const updatedCredentials = {

      newRefreshToken: await refreshToken2(),
      newExpiresOn: response?.expiresOn,
    };

    return updatedCredentials;
  } catch (error) {
    // Handle token refresh failure
    throw new Error(error as string | undefined);
  }
};


//Get all calendar service
const getAllCalendarServices = async (
  req: Request,
  user: string,
): Promise<any> => {
  const account = await AccessTokenModel.findOne({
    user,
    provider: 'microsoft',
  })
    .sort({ createdAt: -1 })
    .limit(1);

      message: 'Kindly authorize the microsoft App to continue',
    };
  }

  if (account.expiryTime.getTime() < Date.now()) {
    const newTokens = await refreshAccessToken(account.refreshToken, req);

    await AccessTokenModel.findOneAndUpdate(
      { user, provider: 'microsoft' },
      {
        accessToken: newTokens.newAccessToken,
        expiryTime: newTokens.newExpiresOn,

    // Use the new access token to make the request
    const calendarsResponse = await axios.get(
      'https://graph.microsoft.com/v1.0/me/calendars',
      {
        headers: {
          // eslint-disable-next-line @typescript-eslint/restrict-template-expressions
          Authorization: `Bearer ${newAccount?.accessToken}`,
        },

  const calendarsResponse = await axios.get(
    'https://graph.microsoft.com/v1.0/me/calendars',
    {
      headers: {
        Authorization: `Bearer ${account.accessToken}`,
      },
    },
  );

  return calendarsResponse.data;
};

//Get all calendars controllers
const getAllCalendarsController = async (
  req: Request,
  res: Response,
): Promise<any> => {
  try {
    const user = req.session.user?.email;
    const allCalendars = await getAllCalendarServices(req, user!);
    return res.status(200).json(allCalendars);
  } catch (error: any) {
    // eslint-disable-next-line no-console
    // console.log('error', error);
    if (error.response.status !== 200) {
      return res.status(error.response.status).json(error.response.data.error);
    }
    return res.status(500).json(error.response.data);
  }
};

Reproduction Steps

1. Set up DB for storing access tokens and refresh tokens. (AccessTokenModel).
2. Import the getAllCalendar service function into your conroller file.
3. Make a call to the getAllCalendarController endpoint.
4. If accesTokenModel.expiry time === true/ access token has expired, endpoint will call the refreshAccessToken to obtain a new accesstoken and refreshtoken.

Here is a link to the sample code on github: SAMPLE OF CODE ON GITHUB

How to run the code.

1. Git clone: Sample code
2. npm install
3. npm run dev
4. Auth endpoint: http://localhost:8000/install
5. callback endpoint : http://localhost:8000/callback
6. Get all calendars endpoin: http://localhost:8000/calendars

Expected Behavior

I expect that the refreshAccessToken function should not only generate new accessTokens but should also store this access token in the cache along with the refresh token in the token cache.
