`ensureAuthorized` token promise bug

const token = sign(decoded, MASTER_PRIVATE_KEY.replace(/\\n/g, '\n'), {

This code is broken. sign returns a promise but it's being assigned to token. Needs to be refactored like this :

          const maybeOfferNewTokenHeader = () => Promise.resolve()
            .then(() => MASTER_PRIVATE_KEY ? sign(
              decoded,
              MASTER_PRIVATE_KEY.replace(/\\n/g, '\n'), {
                algorithm : 'RS256',
                expiresIn : process.env.JWT_TTL || '20s'
              }) : req.get('x-auth-token')
            )
            .then(token => {
              res.set('x-auth-token', token);
            });

          return Promise.resolve(secret)
            .then(verifyRSJWT(verify)(token))
            .then(maybeOfferNewTokenHeader)
            .then(setReqUser)
            .then(() => continueWithErrorIfNotPermitted(axios, checkPermission)(decoded, req, next));
