我一直在尝试使用 Rails 设置 GitHub 操作，但是我遇到了RAILS_MASTER_KEY（我的假设）的问题。

这是我在最后一步收到的错误消息# Build and run tests：

rails aborted!
ActiveSupport::MessageEncryptor::InvalidMessage: ActiveSupport::MessageEncryptor::InvalidMessage

bin/rails:3:in `<main>'

Caused by:
ArgumentError: key must be 16 bytes

.github/workflows/main.yml：

rails aborted!
ActiveSupport::MessageEncryptor::InvalidMessage: ActiveSupport::MessageEncryptor::InvalidMessage

我推断这与我的 RAILS_MASTER_KEY 变量有关。

我检查了存储在项目 ENV 变量中的密钥，它恰好是 32 个字节。我不确定如何最好地进行，并且我对删除密钥犹豫不决，担心我会破坏应用程序的其他部分。在我的书中，将密钥的选项设置为合法的 32 个字节会更可取——只是我不知道如何以及在哪里......

关于如何解决这个问题的任何想法？
