錯誤原因：使用的 Fiori tools CLI 版本過低所致。

"@sap/ux-ui5-tooling": "1.0.10"

解決辦法：使用最新的 `1.4.7` 版本：

![](https://img-blog.csdnimg.cn/img_convert/1100dc678ed2f89f3f9b471a67d0a604.png)

錯誤原因：ui5.yaml 檔案內容不全。

至少應該包含 `fiori-tools-proxy` 區域。

![](https://img-blog.csdnimg.cn/img_convert/70b31c510a7bd49e7c1d38bdbcbd92c3.png)

參考一個格式正確的 `ui5.yaml`:

```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. E.g. self-signed certificates will be accepted
      backend:
      - path: /sap/opu/odata
        url: http://localhost
      ui5:
        path: 
        - /resources
        - /test-resources
        url: https://ui5.sap.com
        version:  # The UI5 version, for instance, 1.78.1. Empty means latest version
  - name: fiori-tools-appreload
    afterMiddleware: compression
    configuration:
     port: 35729

# 錯誤訊息3

原因是 `ui5-deploy.yaml` 檔案中 `deploy-to-abap` 這個自定義 task 的 `target`, 即遠端 ABAP 系統的 url 維護不正確。

![](https://img-blog.csdnimg.cn/img_convert/1ed23320d9a6e3a6cdb38e04aff7bb8f.png)

如果看到上圖所示的提示訊息：

> The deployment destination requires authentication. Please enter your credentials below
? Username:

說明 ABAP 系統連線成功。

# 錯誤訊息4

> Upload canceled, archive could not be read or appears to be empty

![](https://img-blog.csdnimg.cn/img_convert/378d17a60f704da4d1d9fcb1df782586.png)

錯誤訊息和這個[帖子](https://answers.sap.com/questions/13474945/upload-canceled-archive-could-not-be-read-or-appea.html)介紹的一致。

這個錯誤和 `SAP UI5 tools` 的版本有關。

使用 `generator-easy-ui5` 建立的 SAP UI5 專案，`SAP UI5 tools` 的預設版本號如下圖所示：

![](https://img-blog.csdnimg.cn/img_convert/86c9ea62fb256959b9e7fd034b1ec7ec.png)

```json
"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"
        ]
    }
```

解決方案：刪除 `package-lock.json` 檔案和 `node_modules` 資料夾，

執行命令列安裝最新版本：

>  npm install @sap/ux-ui5-tooling@latest

![](https://img-blog.csdnimg.cn/img_convert/da0be169acb8549ff54bfc6f625c5c39.png)

成功安裝的版本號：`1.4.7`
![](https://img-blog.csdnimg.cn/img_convert/129c913587192e8831e99f3de42c38da.png)

將 `package.json` 檔案裡的 `deploy` 指令碼命令更改為：

> npm run build && fiori deploy --config ui5-deploy.yaml
![](https://img-blog.csdnimg.cn/img_convert/7b0fea0898032767de3ac8167c513650.png)

重新執行 `npm run deploy` 即可：

解決辦法是，提前在 ABAP 系統 ER9 `手動建立`好 BSP 應用即可：
