我正在运行超级账本网络。我正在使用fabricjs的余额转移示例以及使用nodejs sdk来运行网络的步骤。 我已经在网络中的组织中注册并注册了新用户，并且成功，但是在创建面对错误的频道时- 被禁止的原因：隐式策略评估失败-满足0个子策略，但是此策略要求满足“作家”子策略中的1个：权限被拒绝
响应如下：-
POST request Create channel ...
{"success":false,"message":"Channel 'Mychannel' failed to create status:FORBIDDEN reason:implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Writers' sub-policies to be satisfied: permission denied"}
在日志中：-
