InternalOAuthError: failed to fetch user profile when using passport-linkedin-oauth2

[innocentEdosa]

I am trying to implement LinkedIn social sign in using passport-linkedin-oauth2. following the documentation, this is a cut out of my code

``
passport.use(
new LinkedInStrategy(
{
clientID: "",
clientSecret: "",
callbackURL: ""
scope: ["openid", "email", "profile"],
state: true,
},
async (accessToken, refreshToken, profile, done) => {
done(null, profile)
},
),
)

``

The process to enter the user's LinkedIn credentials is triggered but when my application is granted permissions, I get this error

InternalOAuthError: failed to fetch user profile
at Strategy. (/opt/backend/node_modules/passport-linkedin-oauth2/lib/oauth2.js:57:19)

at endReadableNT (node:internal/streams/readable:1358:12)
at processTicksAndRejections (node:internal/process/task_queues:83:21)

I installed these passport packages and I am currently working with expressjs

 "passport": "^0.6.0",
"passport-linkedin-oauth2": "^2.0.0",


Please I appreciate any help
