Autodesk Forge Error #9排查：无可查看内容及模型翻译失败

核心问题 #

模型转换阶段出现解压失败（Tr worker fail to unzip.），导致无可用衍生数据，触发Viewer Error #9。

解决步骤 #

• 验证模型文件完整性
  重新下载Autodesk示例.rvt模型，对比文件MD5值确认未损坏。上传过程避免中断，大文件建议用官方SDK或分段上传方式，防止文件截断。
• 修正文件上传方式
  不要将模型放在Postman本地目录，通过Postman的二进制上传功能将文件上传至Autodesk OSS服务，确保生成的URN对应云端存储的模型文件，而非本地文件路径。
• 检查Token权限
  确保Token包含data:read和data:write权限，转换模型需要写入权限，加载模型需要读取权限，同时确认Token未过期。
• 重新触发转换任务
  调用Delete Manifest接口删除失败的转换记录，再重新调用Translate Model接口发起转换，指定正确的输出格式（如svf）。
