Linkedin Provider - Sign in Issue

System Information
  • Strapi Version: v4.20.0
  • Operating System: Windows 11
  • Database: better-sqlite3 9.4.0
  • Node Version: v20.9.0
  • NPM Version: 10.2.3
    -** Frontend: Next.js 14

I am trying to add Sign in with Linkedin as the provider. I’ve set everything up on the Linkedin App and on Strapi Admin.
Currently available products on linkedin side are:

Sign In with LinkedIn v2 (custom OAUTH)

Sign In with LinkedIn using OpenID Connect

These are the available scopes:

When following instructions from Users & Permissions | Strapi Documentation everything is fine until i get to this step:

  • Create a frontend route like FRONTEND_URL/connect/${provider}/redirect that have to handle the access_token param and that have to request STRAPI_BACKEND_URL/api/auth/${provider}/callback with the access_token parameter.
    The JSON request response will be { "jwt": "...", "user": {...} }.

I’ve created the route, but when I call this endpoint I get an error 403 Unauthorized.

I did some digging around, and when I console.log out the response from node_modules/@strapi/plugin-users-permissions/server/controllers/auth.js I get an error response
from Strapi backend when trying to issue jwt via provider:

According to this error and Profile API - LinkedIn | Microsoft Learn seems like Strapi is calling linkedin /v2/me endpoint which requires r_liteprofile, r_basicprofile, r_compliance, while Linkedin now is using /v2/userinfo and these scopes: openid, profile, email, and that’s why I’m getting this error.

Did anyone encounter this, or I’m doing something wrong?

Would appreciate any help or advice. Thanks.

similar issue. I followed these steps: Users & Permissions | Strapi Documentation

But if i click the Button “Signup with Linkedin”, I get the Error “Internal Server Error”. the console log of strapi is saying:
Error: Cannot send secure cookie over unencrypted connection
at Cookies.set (/opt/node_modules/cookies/index.js:94:11)
at (/opt/node_modules/koa-session/lib/context.js:341:22)
at ContextSession.commit (/opt/node_modules/koa-session/lib/context.js:244:16)
at session (/opt/node_modules/koa-session/index.js:46:20)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
at async middleware (/opt/node_modules/@strapi/strapi/dist/services/metrics/middleware.js:20:5)

Did not encounter that problem.

This might help someone:
I’m using next.js on the frontend and next-auth for authentication, I solved this issue by using LinkedIn provider from next-auth that calls LinkedIn and gets data about the user from LinkedIn, if response is valid, I am then calling a custom endpoint in Strapi which I created that is handling user auth on Strapi side and issuing jwt which is then sent to next auth to login the user.
