STEP translation fails in DEU region with empty manifest, same file succeeds in US
05:59 28 Sep 2026

All STEP files fail to translate in the DEU region: the manifest ends with "status": "failed", no derivatives and no error message. The identical file and job succeed in the US region. health.autodesk.com reports no outages.

Files:

  • Different STEP files tested, all of them fail
  • Open without issues in Autodesk Viewer and in Open CASCADE (CAD Assistant)

Steps to reproduce:

# 1. Bucket in DEU (verified afterwards with GET /oss/v2/buckets?region=DEU)

curl -X POST "https://developer.api.autodesk.com/oss/v2/buckets" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -H "x-ads-region: DEU" \
  -d '{"bucketKey":"","policyKey":"transient"}'

# 2. Upload the file via signeds3upload (GET signed URL, PUT file, POST to complete)

# 3. Start translation in DEU

curl -X POST "https://developer.api.autodesk.com/modelderivative/v2/designdata/job" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -H "region: DEU" -H "x-ads-force: true" \
  -d '{"input":{"urn":""},"output":{"formats":[{"type":"svf","views":["2d","3d"]}]}}'

# 4. Poll the manifest

curl "https://developer.api.autodesk.com/modelderivative/v2/designdata//manifest" \
  -H "Authorization: Bearer $TOKEN" -H "region: DEU"

The job is accepted ("result": "success"). After about 30 seconds the manifest is:

{
  "type": "manifest",
  "hasThumbnail": "false",
  "status": "failed",
  "progress": "complete",
  "region": "DEU",
  "version": "1.0",
  "derivatives": []
}

There is no messages entry anywhere, so there is nothing to act on.

We've ruled out:

Test Result
Same file, same job, US bucket + region: US ✅ succeeds in ~30 s
DEU, svf2 instead of svf ❌ same empty failure
DEU, second, independent APS app ❌ same empty failure
DEU, fresh transient bucket vs our production bucket ❌ both fail
Cross-region setup ruled out: bucket regions verified via GET /oss/v2/buckets?region=..., and the job's region header matches the bucket
Other formats in the same DEU bucket (.nwd, .obj) ✅ translate fine
The same geometry exported to OBJ, translated in DEU ✅ succeeds

Reproduced consistently from 2026-09-25 to 2026-09-28, so it doesn't look like a transient outage.

Questions:

  1. Is there a known issue with the STEP translator in the DEU region, or a version difference between DEU and US?
  2. Is there any way to get a diagnostic message for a job that fails with an empty derivatives array?
  3. Is there a supported workaround that keeps the data in DEU (e.g. a translator option), other than converting the file to another format first?
