OSS_UNIMPLEMENTED
OSS_UNIMPLEMENTED (0x80093019) is an OSS ASN.1 runtime result for requested runtime feature is not implemented. The selected codec, representation, or operation reaches a feature that this runtime edition or version does not provide. Because type representation and encoding rule is central to this condition, Microsoft’s HRESULT range and the OSS Nokalva return-code documentation should be read together. Start the investigation by recording runtime product, edition, and exact version, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Locate the failing codec stage
At the requested runtime feature is not implemented boundary, capture the first OSS function returning the value and note whether the operation was encode, decode, copy, compare, constraint validation, or trace setup. Preserve the selected PDU, encoding rules, and compiler directives affecting generated representation; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Evidence worth preserving
- type representation and encoding rule
- runtime product, edition, and exact version
- compiler directives affecting generated representation
A controlled way to reproduce it
- Reduce the schema to the unsupported construct
- Check a newer supported runtime with identical input
- Avoid changing wire rules merely to hide the result
What not to confuse it with: the result
TYPE_NOT_SUPPORTED is tied to an ASN.1 type; UNIMPLEMENTED can identify a broader operation or representation feature.
Instrumentation
Where type representation and encoding rule can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use runtime product, edition, and exact version together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Exit criteria: the result
Select a supported representation or runtime release and add a compatibility test before deployment.
