在 heroku 上部署 nextjs fronend 和 nodejs 后端错误

问：

我正在尝试部署这个具有目录的应用程序：在此处输入图像描述

我添加了一个 procfile。但是当我尝试使用命令将其推送到master时：heroku git:remote -a pet-finder-1 git add . git commit -m "deply git push heroku master

它给了我错误：

 HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/pet-finder-1.git'

我尝试使用这些命令设置构建包：但没有一个有效heroku buildpacks:set heroku/nodejs -a pet-finder-1

更新：

在设置构建包并在根目录下创建package.json后，使用

npm init -y

我收到了以下新错误：
