我正在使用私有数据集合设置具有 3 个对等点和 3 个组织的自定义 Hyperledger Fabric v1.2 区块链网络。侧数据库是 CouchDB。我使用 fabric-node-sdk 连接到区块链。链码被实例化，没有任何错误，但不能调用将数据放入集合的链码方法。
以下错误显示在实例化链码的对等方的 docker 日志中，该对等方也是交易的背书对等方：

请注意，集合所需的对等点数是 3。显然，即使每个对等点都有自己的 couchdb 容器，数据甚至也不存储在背书对等点本身的侧数据库中。
couchdb 容器记录如下错误。除此之外，它们似乎工作正常。

为什么侧数据库中没有存储私有数据，为什么传播失败？
提前致谢。
