无法获取Revit Filemeta数据或在3D查看器中查看Forvit模型衍生API的Revit模型

Question

We have been using the model derivative api endpoints to extact data from forge but are currently having issues extracting meta data when uploading specifically Revit files.

Our process goes:

1. Auth

2. Upload a model in chunks https://developer.api.autodesk.com/oss/v2/buckets/ {bucketKey}/objects/{objectName}/resumable

3. Create upload job https://developer.api.autodesk.com/modelderivative/v2/designdata/job

4. Get translation the process https://developer.api.autodesk.com/modelderivative/v2/designdata/ {encodedUrn}/manifest

5. Get the object from the forge https://developer.api.autodesk.com/modelderivative/v2/designdata/ {encodedUrn}/metadata

Current we are we receive a 200 response from step 5 with and empty meta information so we cannot extract anything.

When we load the 3D viewer (versions 6.0 and 4.0) the viewer calls the https://developer.api.autodesk.com/derivativeservice/v2/manifest/

When

"messages": [
            {
                "type": "error",
                "code": "Revit-UnsupportedFileType",
                "message": "<message>The file is not a Revit file or is not a supported version.</message>"
            },
            {
                "type": "error",
                "message": "Possibly recoverable warning exit code from extractor: -536870935",
                "code": "TranslationWorker-RecoverableInternalFailure"
            }
        ],

It was converted from an ifc format if that helps in any way. We have tried this file in 360 and in forge with both revit and ifc before and translation has worked. I can provide a urn also.

Answer 1

As reported by @Glenit, it was missing some pieces on the resumable upload. For reference, this answer points out some samples on it.
