Hyperledger Composer :error Authenticating to the

Question

I have been following this Hyperledger Composer tutorial here and when I try to authenticate to the rest server via http://localhost:3000/auth/github I am not being redirected to the GitHub site to perform the OAuth web server authentication flow. Instead of redirecting, I am getting a 404 error message. Expected Behavior

According to the Composer tutorial, I would expect being redirected to the Github site to perform the OAuth. Actual Behavior

When I enter http://localhost:3000/auth/github I am getting a 404 error

My environment:

docker --version Docker version 17.03.1-ce, build c6d412e

docker-compose --version docker-compose version 1.13.0, build 1719ceb

node --version v6.11.0

Adding more details for reference...

EDIT:

here is complete error stack trace:

Answer 1

Check if your github account is private. I created a new github account, and it works. Also use the latest command:

composer-rest-server -p hlfv1 -n my-network -i admin -s adminpw -a true

instead of the -S one

Good luck!

Answer 2

in your COMPOSER_PROVIDERS stanza - specifically the callbackURL setting - you don't need the localhost:3000 - you just need the URL path as "/auth/github/callback" shown in the docs : https://hyperledger.github.io/composer/integrating/enabling-rest-authentication.html . The REST server will take care of..the rest.. . Then stop and restart the composer REST server composer-rest-server -p hlfv1 -n my-network -i admin -s adminpw -S true etc - from the command line where you export the configuration variable COMPOSER_PROVIDERS (above). cheers Paul
