Question

我正在尝试 Revit 设计自动化教程。我收到以下错误。谁能帮我解决这个错误。

TypeError [ERR_INVALID_ARG_TYPE]: The "chunk" argument must be of type string or an instance of Buffer or Uint8Array. Received an instance of ReadStream

Answer 1

I want to understand what the error means, so it could help me fix the error., though it might be basic.

如果您的目标是了解这个特定的错误，那么您可以阅读 question/answer 最好的地方 asked/explained。然而，由于这是来自 Forge 的 nodejs api，我认为你没有编写这段代码，你不应该关心它。

我最好的猜测是您以某种方式设法将 nodejs 软件包 forge-api 升级到 0.9.0，而教程的其余部分 repo/code 与它不兼容。您可以使用以下命令进行检查：

cd {repo_folder}
npm ls -depth=0

您应该会看到以下结果：

├── autodesk.forge.designautomation@3.0.5
├── body-parser@1.20.0
├── cookie-session@1.4.0
├── express@4.18.1
├── forge-apis@0.8.6
├── form-data@4.0.0
├── multer@1.4.4
└── socket.io@4.5.1

如果您的 forge-apis 显示的是 0.9.0 而不是 0.8.6，则说明了您遇到的错误。要降级它，您可以删除 node_modules 文件夹，再次撤消对 package.json and/or package-lock.json 和运行 npm install 的任何更改。

或者，您也可以显式降级 forge-api 模块。

cd {repo_folder}
npm install forge-apis@0.8.6 -save
npm ls -depth=0

Answer 2

感谢 Rahul 发现问题！我可以在 0.9.0 中重现@JohnKuldeepRoshanKerketta 在 Forge SDK (forge-apis) 中的体验。根据错误提示，我更新了 tutorial code(line 509,510) 以使用 readFile，而不是文件流。现在它适用于 0.9.0.

我发布了 Issue with tutorial https://github.com/Autodesk-Forge/learn.forge.designautomation/issues/31

// 2. upload inputFile
const inputFileNameOSS = `${new Date().toISOString().replace(/[-T:\.Z]/gm, '').substring(0,14)}_input_${_path.basename(req.file.originalname)}`; // avoid overriding

try {
    //let contentStream = _fs.createReadStream(req.file.path);

    let fileContent = _fs.readFileSync(req.file.path);

    await new ForgeAPI.ObjectsApi().uploadObject(bucketKey, inputFileNameOSS, req.file.size, fileContent, {}, req.oauth_client, req.oauth_token);
}
