Hey onroute! I’d be happy to offer some assistance if I can. Could you post the code? And the error from Auth0 logs would be helpful too. I’ve used the checkSession method with both auth0-js and auth0-lock and haven’t encountered this issue.
My javascript code looks something like this:
this.lock.checkSession({}, (err, authResult) => {
if(err) {
console.log(err);
} else {
const expiresAt = JSON.stringify((authResult.expiresIn * 1000) + new Date().getTime());
localStorage.setItem('access_token', authResult.accessToken);
localStorage.setItem(expires_at);
}
});
