我目前正在尝试设置 GitHub 操作，以自动构建后端并将其推送到 DockerHub。但是，如果触发了工作流，它将开始创建 Docker 映像，但在以下行中build-and-deploy-backend失败：23server/Dockerfile

  22 |     COPY ./src ./src
  23 | >>> COPY ./tsconfig.json ./

见：https ://github.com/bennodev19/dronies-watch/runs/4813916640?check_suite_focus=true

出现此错误：

Dockerfile:23
--------------------
  21 |     # Move required app source into the working directory referenced with './'
  22 |     COPY ./src ./src
  23 | >>> COPY ./tsconfig.json ./
  24 |     
  25 |     # For debugging:
--------------------
error: failed to solve: failed to compute cache key: "/tsconfig.json": not found
Error: buildx failed with: error: failed to solve: failed to compute cache key: "/tsconfig.json": not found

见：https ://github.com/bennodev19/dronies-watch/runs/4813916640?check_suite_focus=true

在本地它构建没有任何问题。MacOS在和上测试Windows 10。
