OSS_OPEN_TYPE_ERROR
OSS_OPEN_TYPE_ERROR (0x8009302C) is an OSS ASN.1 runtime result for automatic open-type processing failed. The runtime could not automatically encode, decode, copy, or resolve an ASN.1 open type whose concrete type depends on surrounding object-set information. Because governing OID or unique key 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 information object set and table used for lookup, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Where processing stopped
At the automatic open-type processing failed 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 raw open-type bytes and selected concrete type; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Isolation sequence
- test the discriminator with a known registered value
- decode the raw field separately only for diagnosis
- verify object-set extensions are present on both sides
Facts that change the conclusion
| Record | Diagnostic value |
|---|---|
| governing OID or unique key | Locates the concrete message, allocation, module, or API boundary |
| information object set and table used for lookup | Separates payload-dependent behavior from build and process state |
| raw open-type bytes and selected concrete type | Makes the comparison reproducible without rewriting the original artifact |
Similar names, different faults: the result
An open type may be well-formed bytes yet still fail because its discriminator has no matching type or the automatic copy/compare callback fails.
Keep the original bytes or object graph unchanged while testing test the discriminator with a known registered value. A change in information object set and table used for lookup after reload, plugin replacement, restart, or schema deployment is evidence about runtime state, not permission to discard the reproducer. When raw open-type bytes and selected concrete type points to one message, retain a cryptographic hash and the smallest safe sample instead of logging certificate, subscriber, credential, or private-key material.
Instrumentation
Record the full 32-bit HRESULT and lower OSS return number together with operation direction, symbolic PDU, encoding rule, byte count, and generated-table identifier. Where governing OID or unique key can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use information object set and table used for lookup together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Decision matrix
| Controlled observation | Conclusion it supports |
|---|---|
| test the discriminator with a known registered value | A changed outcome isolates the first proposed control instead of a blind retry |
| governing OID or unique key differs between success and failure | The difference localizes the automatic open-type processing failed boundary before unrelated settings are changed |
| An independent decoder accepts the same artifact | Inspect generated schema, selected rules, ABI, and optional OSS modules before declaring the bytes invalid |
| A fresh control object changes the outcome | Investigate initialization, lifecycle, allocator ownership, configuration mutation, and concurrent access |
Completion check: the result
Align the discriminator table with the schema and preserve an unknown-extension test that follows the protocol’s rules. A recovery test built around test the discriminator with a known registered value should replay the same operation under the same schema and encoding rule, retain one deliberately invalid control, and verify ownership and cleanup after both outcomes. Success after an unexamined retry is not proof that governing OID or unique key now satisfies the codec contract.
