查看问题中包含的日志，您的custom图像可能有问题。在日志文件的第7行中，它警告未找到目录“/mse-tsm-cloudsys-labl1/app/”：

Oct  6 19:25:22 frontend-lab1 GCEMetadataScripts[795]: 2021/10/06 19:25:22 GCEMetadataScripts: startup-script: /tmp/metadata-scripts111777770/startup-script: line 3: cd: /mse-tsm-cloudsys-lab1/app/: No such file or directory

如果此目录用于包含您的应用程序文件，则可能会导致与NPM无法找到package.json等文件以及属于您的应用程序的其他文件相关的后续错误

您应该确认应用程序路径是否正确，或者映像是否正确创建。您可以按照this指南从现有VM实例创建自定义映像，并使用Node.js和Python指南确保遵循正确的步骤
