无法运行示例 Activiti Cloud 应用程序

Question

我正在尝试在 docker 中运行 Activiti Cloud 示例。
我正在使用这个官方教程：
https://activiti.gitbook.io/activiti-7-developers-guide/getting-started/getting-started-activiti-cloud/getting-started-docker-compose

前面的步骤全部成功直到我尝试
“要开始工作，请在 Postman Keycloak 集合中执行 getKeycloakToken hruser。然后在 rb-my-app Postman 集合中运行 startProcess。”

我成功在Postman Keycloak集合中执行getKeycloakToken hruser。
我无法在 rb-my-app Postman 集合中运行 startProcess 。

当我在 Postman 建模集合中执行 getModels 时，得到 404。
当我在 Postman rb 集合中执行 startProcess 时，我得到了 500 。

日志中主要错误信息：
