I'm trying to run the following blockchain tutorial on Windows 10 https://hyperledger.github.io/composer/tutorials/developer-guide.html

Everything went fine (all npm installs, fabric tools, download fabric, start fabric, create the project archive, composer runtime install) untill I ran the following command:

composer network start --card [email protected] --networkAdmin admin --networkAdminEnrollSecret adminpw --archiveFile [email protected] --file networkadmin.card

And had this error:

Starting business network from archive: [email protected] Business network definition: Identifier: [email protected] Description: Tuto DevWorks

× Starting business network definition. This may take a minute...

Error: Error trying to instantiate composer runtime. Error: Error: Invalid results returned ::NOT_FOUND
Command failed

My configuration is:

  • WIN 10

  • Node v8.9.1

  • npm 5.5.1

  • Docker version 17.09.0-ce, build afdb6d4

  • git version 2.14.1.windows.1

I also tried with another bna archive and had the same issue. Thanks for your help!

If this message occurs on the stage of instantiating the composer chaincode, you must check if a fabric channel is defined and peers have joined it.
