I am running composer playground locally and while I am connected to the Internet, it is unable to load the sample business networks when I attempt to deploy a new business network. I get following error message:

Error: could not get any sample networks.

  • its probable it doesn't know how to get out to the sample-networks on the NPM registry - how did you install composer playground incidentally? - also, are you using Composer v0.19.x / 1.1 of Fabric ? At first glance, it would seem it can't get out to the NPM repository to install them. The samples are also out on Github repo https://github.com/hyperledger/composer-sample-networks/tree/master/packages – Paul O'Mahony Jul 18 '18 at 11:17
  • It looks like there is some issue with the npm registry servers and its search capabilities at the moment which is causing the problem as playground makes a search request to the npm registry for available samples – david_k Jul 18 '18 at 12:55
  • I'm having the same issue. I also tried https://composer-playground.mybluemix.net/ and it seems not working either. – Shawn Song Jul 18 '18 at 13:46
  • I am facing same issue. on cloud composer playground is showing the same thing. no change! – Sahil Jul 20 '18 at 02:15
  • There is still a problem with the NPM search facilities. We have released a version that uses a different repository search and is available at http://composer-playground-unstable.mybluemix.net/. – david_k Jul 20 '18 at 16:49

Had the same issue. Make sure u have all your 3 Docker containers are up and running. So here is how it goes :

When u run locally, u gotta run Docker containers on your local machine.

When u want to deploy, u can do so in the Docker file or also upload to Docker hub and call the images from that path.

Good luck mate.

  • Thanks for the answer. Unfortunately, if you can please walk me through it, I am pretty new to this environment. – Pranav Vyas Jul 21 '18 at 04:01
  • Update: I checked docker container list with "docker ps" command. I restarted all with "docker restart" command. Now I am unable to start playground with command "container-playground". It is giving me following error: "Error: Object with ID 'undefined' in collection with ID 'chaincodes' does not exist". – Pranav Vyas Jul 21 '18 at 04:16
  • Update 2: cleared cookies in browser and its working now. – Pranav Vyas Jul 21 '18 at 04:37

This error could be due to the fact that Composer Playgrounds (cp) is looking to a previous project. Besides the deletion of browser cookies for localhost:cp-listening-port (8080 by default), check that that your browser points to:

http://localhost:cp-listening-port/login
