I setup a supertokens node in my application A. But I wanted to verify session in another application that is an http proxy for combining microservices for local development purposes you can consider like an api gateway. I am trying to verify session just before proxying to other microservices so I can add custom header that contains user information. But when I try to connect supertokens node on that proxy application, my main application A's overrided methods are not working also it does not send emails via application A. What kind of approach should I apply on that scenario?

hey @syntaxerror do you have any sort of path that is stripped away by the proxy server before forwarding the request to the actual server?

no ``` supertokens.init({ framework: "express", supertokens: { connectionURI: "http://localhost:3567", }, appInfo: { appName: "myapp", apiDomain: "http://localhost:8000", websiteDomain: "http://localhost:8080", apiBasePath: "/auth", websiteBasePath: "/" }, recipeList: [ Passwordless.init({ flowType: "USER_INPUT_CODE", contactMethod: "EMAIL_OR_PHONE" }), Session.init() ] }); app.use(cors( { credentials: true, origin: "http://localhost:8080", allowedHeaders: ["content-type", ...supertokens.getAllCORSHeaders()], } )) app.use(ex.middleware()); app.use(ex.errorHandler()) app.use(expressContext()) const addHeaders = async (proxyReq, req, res) => { if (req.context.userId === undefined) { console.log("session undefined") }else{ console.log("session defined") proxyReq.setHeader("X-User-ID", req.context.userId); } } app.use(async (req, res, next) => { try { let session = await Session.getSession(req, res); if (session === undefined) { throw Error("Should never come here") } let userId = session.getUserId(); req.context.userId = userId console.log("userId", req.context.userId) next(); } catch (err) { next(err); } }) ``

can you enable backend debug logs and show the output when you call one of the APIs which you have added override on?

Actually, I inited another application too.

i don't think i am understanding the setup

May be my approach is wrong, let me show what I'm trying: APP-A(has overrided methods) -> SuperTokens Core(runs under docker) APP-PROXY-> trying to verify session and adding header to just before proxying to microservices. But I want to connect via APP-A. In summary User -> app-proxy -> App-A -> Supertokens-core

right. So how are you verifying the session in APP-PROXY? Are you using getSession / verifySession function?

app.use(async (req, res, next) => { try { let session = await Session.getSession(req, res); if (session === undefined) { throw Error("Should never come here") } let userId = session.getUserId(); req.context.userId = userId console.log("userId", req.context.userId) next(); } catch (err) { next(err); } })

"express proxy application creates its own instance" -> instance of?

So that It does not connect to App-A I have already created logics on it.

Ah i see.

post-signin post-signup consumecode override and I have own businessrules while consuming code etc.

right. So when calling APIs related to supertokens (sign in etc..) don't call the getSession in proxy-app and just pass the request to app-A. For other requests, call the getSession and pass it to wherever your application's APIs are defined.

yeah it is quite reasonable. I will try and give you the feedback.

We have guides for AWS integration - should check those out

I think I can bind my custom authorizer on necessary paths right

yea. custom authorizer works - we also have code snippet for that

thanks 👍
