Hi again. I have implemented an auth flow with expressjs server + react native on localhost, ngrok and Hasura before. It was working great. Today I have switched to a vercel app following the example here https://github.com/supertokens/supertokens-auth-react/blob/master/examples/with-emailpassword-vercel/api/index.js. Again everything works fine except SuperTokens.getAccessTokenPayloadSecurely()).jwt. When I try to get the JWT it returns

Could not refresh session

error.

You can see the session init here. JWT is enabled and issuer is set to vercel auth path. I would really appreciate any ideas.

Can you enable debug logs on the backend and then query that? And show me the Log output

See the troubleshooting section on how to enable debug logs

I can pass DEBUG=com.supertokens arg when running vercel on localhost like

DEBUG=com.supertokens vercel dev

but not sure how to achieve that with vercel deploys. I have tried adding

"vercel-build": "DEBUG=com.supertokens node ./api/index.js"

to package json but even though I can see the logs the build never gets completed.

With localhost

vercel dev

everything works perfect though. I can get the JWT with

(await SuperTokens.getAccessTokenPayloadSecurely()).jwt

without any issues.

What is the appInfo that you have configured on the backend and frontend? During production deployment

My production backend at /api/index.js: https://gist.github.com/solminded/bd628f08313b86e74168392d33b00e70

My frontend app info:

Copy code

SuperTokens.init({
    apiDomain: https://akasa-audiobook-auth-server-offminded.vercel.app,
    apiBasePath: '/api/auth'
});

Backend app info:

Copy code

appInfo: {
      appName: my-project-audiobook,
      apiDomain: https://akasa-audiobook-auth-server-offminded.vercel.app,
      websiteDomain: https://akasa-audiobook-auth-server-offminded.vercel.app,
      apiBasePath: '/api/auth',
      websiteBasePath: '/auth',
    },

When you query doesSessionExist on the frontend, does it work correctly?

rp_st

05/03/2022, 10:29 AM

Does doing an API call that requires session verification work correctly?

solminded

05/03/2022, 10:30 AM

Yes.

solminded

05/03/2022, 10:31 AM

Yeah, seems to be working. DoesSessionExist returns true and right after that I try to get jwt and it fails.

rp_st

05/03/2022, 10:32 AM

Hmm. That’s really strange.

rp_st

05/03/2022, 10:33 AM

Can you delete the sAccessToken cookie and then make an API call that requires a session?

rp_st

05/03/2022, 10:33 AM

Does it refresh the session automatically?

solminded

05/03/2022, 10:34 AM

Let me try that

solminded

05/03/2022, 4:50 PM

Ok I have tried and my vercel backend does not seem to be able to refresh session properly.

solminded

05/03/2022, 4:51 PM

I have given up trying with vercel and moved my backend to Heroku. All working fine with it.

solminded

05/03/2022, 4:52 PM

It might be something to do with vercel node runtime config. Memory or max duration might be the factor here not sure.

rp_st

05/03/2022, 5:07 PM

Hmm. We have tried to deploy app with vercel and it works all fine. But if you got it to work in heroku, then I guess that’s good enough!
