我目前正尝试在Railway上部署一个简单的Notes应用程序，这是课程挑战的一部分。问题是当我尝试部署它时，我得到了以下消息：

#13 ERROR: executor failed running [/bin/bash -ol pipefail -c npm run build]: exit code: 1
 
-----
> [stage-0  9/10] RUN --mount=type=cache,id=s/b5d79573-cbdb-4229-892e-e66e9714107f-node_modules/cache,target=/app/node_modules/.cache npm run build:
-----
 
executor failed running [/bin/bash -ol pipefail -c npm run build]: exit code: 1
 
Error: Docker build failed`

I don´t know if i have a step missing or what could be the problem.

Full deploy log looks like this:

我也试着在www.example.com上部署它render.com我想的是，也许我必须在我的react应用程序中运行run build才能让它工作？抱歉代码太长，这是我第一次部署，我真的被这部分卡住了。
