04/01/2022, 9:53 PMWe're using NodeJS supertokens SDK + managed service in production and as of today all backend verifySession() middleware calls are returning 401. Is something wrong with the managed service?

rp
04/01/2022, 9:57 PMHey. Nothing in particular. Are you using self hosted? Which version of the SDK?
m
mrserif
04/01/2022, 9:57 PMI'd upgraded to 9.1.1 with a deployment today
mrserif
04/01/2022, 9:58 PMI tried reverting back to 8.6.0, but that's also returning 401 in verifySession
mrserif
04/01/2022, 9:58 PMthe service has worked flawlessly for us up till now
r
rp
04/01/2022, 9:59 PMReally strange
rp
04/01/2022, 9:59 PMWhich recipe?
m
mrserif
04/01/2022, 9:59 PMconst { verifySession } = require('supertokens-node/recipe/session/framework/express')
const EmailPassword = require('supertokens-node/recipe/emailpassword')

04/01/2022, 10:00 PMWhat does sign in return?
rp
04/01/2022, 10:00 PMCan I see the response headers?
m
mrserif
04/01/2022, 10:02 PModd
mrserif
04/01/2022, 10:02 PMit just came back
mrserif
04/01/2022, 10:02 PMand is now working
r
rp
04/01/2022, 10:02 PMReallly strange
m
mrserif
04/01/2022, 10:02 PMyeah, I didn't even revert anything
mrserif
04/01/2022, 10:02 PM🤔
r
rp
04/01/2022, 10:03 PMIf it happens again, please do capture the following:
rp
04/01/2022, 10:04 PM- response headers from sign in api call
rp
04/01/2022, 10:04 PM- any browser console log
rp
04/01/2022, 10:04 PM- any backend API error log
m
mrserif
04/04/2022, 12:13 PMOk, was able to reproduce this morning
r
rp
04/04/2022, 12:14 PMalright! Tell me more please.
m
mrserif
04/04/2022, 12:14 PMThis is in localhost - not on production - but same situation seems to apply
mrserif
04/04/2022, 12:14 PMSignin response headers ^
mrserif
04/04/2022, 12:15 PMFollowing api request headers look like this
r
rp
04/04/2022, 12:15 PMRight. I see.
m
mrserif
04/04/2022, 12:15 PMThe 401 is of course because the cookie is missing
r
rp
04/04/2022, 12:15 PMDo you use axios or fetch?
m
mrserif
04/04/2022, 12:15 PMAxios
mrserif
04/04/2022, 12:15 PMhappy to switch if it's causing issues
mrserif
04/04/2022, 12:15 PMour codebase is pretty small
r
rp
04/04/2022, 12:15 PMAdded supertokens' interceptors to add axios instances?
m
mrserif
04/04/2022, 12:15 PMyep! Flow works in general
r
rp
04/04/2022, 12:15 PMno need to switch. Should work well with axios as well.
m
mrserif
04/04/2022, 12:16 PMthis only seems to happen in our application when you have multiple tabs / windows open and you log into different user accounts
r
rp
04/04/2022, 12:16 PMfrom the request headers, it seems that the interceptor was not applied
m
mrserif
04/04/2022, 12:16 PMI was testing across a couple different organizations when the reproducer occurred
mrserif
04/04/2022, 12:16 PMSo I'm guessing I'm not handling logout correctly
mrserif
04/04/2022, 12:16 PMor doing session invalidation properly?
r
rp
04/04/2022, 12:16 PMare you querying an API that is != to the apiDomain value in supertokens.init?
m
mrserif
04/04/2022, 12:16 PMnope, that doesn't ever change
r
rp
04/04/2022, 12:17 PMhuh.. can we get on a quick call to debug this?
m
mrserif
04/04/2022, 12:17 PMsure!
mrserif
04/04/2022, 12:17 PMI tell you what
mrserif
04/04/2022, 12:17 PMgive me a few more minutes to get a 100% reproducible flow
mrserif
04/04/2022, 12:17 PMthen we can walk through the code path
r
rp
04/04/2022, 12:17 PMcool! lmk
m
mrserif
04/04/2022, 12:17 PMthe issue is "fixed" when I kill my browser window
mrserif
04/04/2022, 12:17 PMso something's definitely up with my frontend state
mrserif
04/04/2022, 12:18 PMI just need to figure out what it is 🙂
r
rp
04/04/2022, 12:19 PMi see. Lmk if you would like to hop on a call
rp
04/04/2022, 12:19 PMCan debug this together as well.
m
mrserif
04/04/2022, 12:28 PMOK! I figured it out
mrserif
04/04/2022, 12:28 PMso - Axios interceptors were initialized in a vue component instead of main
mrserif
04/04/2022, 12:29 PMwhen you logged into multiple different windows, the oldest window would throw an error
mrserif
04/04/2022, 12:29 PMthat error would cause the component that normally initialized axios interceptors to bail out
mrserif
04/04/2022, 12:29 PMmoving the init all the way up to main.js resolves the issue, as interceptors are applied before any component loading
mrserif
04/04/2022, 12:30 PMthanks again for offering support 🙂
r
rp
04/04/2022, 12:32 PMok awesome!! :))
