Forge Design Automation Revit教程错误

Question

我正在尝试设计自动化教程进行修订。 我遇到以下错误。 有人可以帮助我解决此错误。

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

感谢拉胡尔发现这个问题！我可以重现@johnkuldeeproshankerketta在0.9.0中以Forge SDK（Forge-apis）经历的内容。根据错误的提示，我更新了教程代码（第509,510行）使用readfile而不是文件流。现在，它可以与0.9.0合作。

我发布了教程的问题
https://github.com/autodesk-forge/learn.forge。 DesignAutomation/Essue/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);
}

我想了解错误的含义，因此可以帮助我解决错误。尽管它可能是基本的。

如果您的目标是了解此特定错误，那么您可以阅读此问题/答案最好/解释。但是，由于这来自Forge的nodejs apis，因此我认为您没有编写此代码，因此您不应该关注它。

我最好的猜测是，您已经设法升级了nodejs package forge-api 0.9.0和其他教程repo/code的其余部分与它不兼容。您可以使用以下命令进行检查：

cd {repo_folder}
npm ls -depth=0

您应该查看以下结果：

├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
└── [email protected]

如果您的forge-apis正在显示0.9.0而不是0.8.6 0.8.6 ，然后说明您遇到的错误。要降级它，您可以删除node_modules文件夹，请删除对package.json.json和/或package> package> package-lock.json的任何更改，然后运行npm安装。

另外，您也可以明确降级forge-api模块。

cd {repo_folder}
npm install [email protected] -save
npm ls -depth=0
