Hi team, when I implement this code, I got error Failed to verify access token I am using "supertokens-node": "13.4.1" with Express and already setup this https://supertokens.com/docs/passwordless/custom-ui/init/backend#3-add-the-supertokens-apis--cors-setup This happen when I leave the browser and come back after a few hours but this will be gone if I clear the cookies on browser and login again. What should I do to avoid this?

import Session from 'supertokens-node/recipe/session';
const session = await Session.getSession(req, res, { sessionRequired: false });
if (session !== undefined) {
   let userId = session.getUserId();
}

hey @hwihwi6108 this is expected. It happens when the access token has expired. Our frontend SDK should do an auto refresh in this case. Can i see the API request being made? Specifically, the request headers.

Hi @rp_st here it is

right. if this returns 401, it should do an auto refresh.

but after a few hours or even a day I come back to browser It throws Error: Failed to verify access token at /node_modules/supertokens-node/lib/build/recipe/session/accessToken.js:89:19 Anyway I can prevent or workaround with it?

no way to prevent that. It should trigger an auto refresh

Thanks @rp_st , now it works OK now with 401 then refresh and 200

right. So if you set it back to the default value, then try again after sometime.. it should work fine. If you get this error again, please let us know
