错误1
(node:28340) UnhandledPromiseRejectionWarning: TypeError: Cannot read property ‘customMiddleware’ of undefined at handleABAP (C:\Code\UI5\Walkthrough\35\node_modules@sap\ux-ui5-tooling\dist\cli\cmd\add-deploy-config.js:113:29)
错误原因：使用 Fiori tools CLI 由于版本过低。
“@sap/ux-ui5-tooling”: “1.0.10”
https://www.npmjs.com/package/@sap/ux-ui5-tooling
解决方案：使用最新的 1.4.7 版本：
错误消息2
Error: Cannot find proxy middleware config in [C:\Code\UI5\Walkthrough\35\ui5.yaml] at f (C:\app\node-v12.18.3-win-x64\node_modules@sap\generator-fiori\generators\deployment-generator\abap\index.js:2:616172) at Object.r.handleErrorMessage (C:\app\node-v12.18.3-win-x64\node_modules@sap\generator-fiori\generators\deployment-generator\abap\index.js:2:616358)
错误原因：ui5.yaml 文件内容不完整。
至少要包括 fiori-tools-proxy 区域。
参考正确的格式 ui5.yaml:
specVersion: '1.0' metadata: name: 'project1' type: application ui5Theme: sap_fiori_3 server: customMiddleware: - name: fiori-tools-proxy afterMiddleware: compression configuration: ignoreCertError: false # If set to true, certificate errors will be ignored.

Empty means latest version - name: fiori-tools-appreload afterMiddleware: compression configuration: port: 35729 path: webapp 错误消息3
info builder:custom deploy-to-abap Create Archive info builder:custom deploy-to-abap Starting Deployment.on project1 ?

原因是 ui5-deploy.yaml 文件中 deploy-to-abap 这个自定义 task 的 target, 即远端 ABAP 系统的 url 维护不正确。
如果看到上图所示的提示消息：
The deployment destination requires authentication. Please enter your credentials below ? Username:
说明 ABAP 系统连接成功。
错误消息4
Upload canceled, archive could not be read or appears to be empty
错误消息和这个帖子介绍的一致。
这个错误和 SAP UI5 tools 的版本有关。
使用 generator-easy-ui5 创建的 SAP UI5 项目，SAP UI5 tools 的默认版本号如下图所示：
"devDependencies": {
"@ui5/cli": "^2.11.1",
"@ui5/fs": "^2.0.6",
"@ui5/logger": "^2.0.1",
"@sap/ux-ui5-tooling": "1",
"rimraf": "3.0.2"
},
"ui5": {
"dependencies": [
"@sap/ux-ui5-tooling"
]
}
解决方案：删除 package-lock.json 文件和 node_modules 文件夹，
执行命令行安装最新版本：
npm install @sap/ux-ui5-tooling@latest
成功安装的版本号：1.4.7
将 package.json 文件里的 deploy 脚本命令更改为：
npm run build && fiori deploy --config ui5-deploy.yaml
重新执行 npm run deploy 即可：
错误消息5
Remote creation in customer namespace not possible in SAP systems
解决办法是，提前在 ABAP 系统 ER9 手动创建好 BSP 应用即可：
