我在main.go文件中有一个go应用程序，它有一个服务器。服务器运行在localhost:9090上。我有我的货单

applications:
  - name: golang-app
    buildpacks:
      - https://github.com/cloudfoundry/go-buildpack
    memory: 4GB
    disk_quota: 4GB
    instances: 1
    env:
      GO_APP_ENV: prod
    services:
      - go_mariadb-prod

当我用cf push -f manifest.prod.yaml推送应用程序时，一开始一切似乎都在工作。一切都是beeing下载和建立正确的。
但最后它崩溃了，在日志中有这个错误：

我不知道这里出了什么问题。我尝试了很多东西，通过改变manifest.yaml或push命令。但都不管用。
