What happend and What you expected to happen.

执行到trustedflow框架的步骤二，第三步，仿真模式，第5的alice上传密钥"cms --config-file alice.yaml register-data-keys"命令后，报错。我检查了，第4的"register_data_keys"配置alice.yaml文件，格式和内容都没有错，密钥也对应上了。

Reproduction code to reproduce the issue.

报错信息如下：

alice.yaml文件只做了以下变动：
register_data_keys:
  data_keys:
    - 
      # (required) str
      resource_uri: breast_cancer_alice
      # (required) str
      data_key_b64: xxxx###对应上没问题的
