The scenario:

  1. Upload a Revit file to a bucket using the Data Management API.
  2. Request a conversion to SVF job using Model Derivative API POST Job
  3. Poll for status using Model Derivative API GET Manifest

This works most of the times, but occasionally the SVF job fails at some arbitrary point, that is: The manifest status is "failed" and the progress is xx%.

When requesting the job again for the same file it fails in the same way, but with a different progress value. I have seen values in the range from 26% to 99% for the same file. Likewise, the time elapsed varies from few minutes to hours.

This happens most often for "larger" rvt files (~200+ mb).

I have downloaded the file from the bucket and thus checked that it has not been corrupted. In other words, it seems that this is a problem internally in Forge.

The question is of cause: Why does the jobs fail? And how can I prevent it?

  • Hi Henrik~ Could you do me a favor add `x-ads-force: true` to your HTTP request header while calling the `Model Derivative API POST Job` and test it again? You can see more description in here (https://developer.autodesk.com/en/docs/model-derivative/v2/reference/http/job-POST/). – Eason Kang Jun 20 '17 at 14:36

  • Thank you for pointing me to 'x-ads-force: true' - I had forgot about that. But I can't say if that solves the actual problem. As I mentioned this is not a consistent problem. If it shows again I may contact you directly and point you to the actual file. – Henrik Skov Jun 26 '17 at 06:25
  • Thanks for getting back to me. I will gladly help you if this issue takes place again. At that moment, please contact me via the `forge.help@autodesk.com`. Thank you. – Eason Kang Jun 29 '17 at 14:05
