我在IBM Bluemix上啓動了hyperledger fabric starter實例。 我部署了Fabric Composer業務網絡。我可以使用自動創建的管理憑證創建資產,參與者和交易。到現在爲止還挺好。什麼不起作用,但是爲參與者發佈身份。我得到下面的錯誤:無法在fabric fabric業務網絡上爲fabric bluemix實例發佈標識

$ composer identity issue -n businessNetwork -p bluemixProfile -i admin -s 39631b62329d0 -u paul -a "org.notarynodes.businessNetwork.Person#paul" 

2017-03-31T16:34:46.933Z ERROR HFCUtil     
:createIdentity() 
Register request failed

/usr/local/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:417:17"]}}$ 
Error: Invalid affiliation group institution_a Command failed. 

我該如何解決這個錯誤?
