我有我的应用程序目前通过的TeamCity和摇篮的混合部署在AWS Opsworks但我需要利用部署挂钩来执行一些任务，如Liquibase迁移，符号链接等Opsworks的Java部署鱼钩
看样子我有Opsworks认识到正确的RB文件存在于部署文件夹中，但是当它运行它们时，我会看到缺少属性的隐式类型转换错误。我试图手动将这些添加到自定义JSON作为解决方法无济于事。
下面是错误，部署JSON和param，这似乎是导致问题。我只是想知道如何填写属性值并越过错误。提前致谢。

The attribute which seems to be generating the issue:
params {:deploy_data=>{"deploy_to"=>"/srv/www/deploy-name", (tons of skipped params) ..., :name=>nil}
Current JSON under which the error is thrown:
{"deploy": {"deploy-name": {"scm": {"user": "accesskey", "password": "secretkey" }}}}
Adjusted JSON in an attempt to resolve:
{"deploy": {"deploy-name": {"scm": {"user": "accesskey", "password": "secretkey" }}, "name": "deploy-name"}}
