RTC_E_PROFILE_NO_USER_URI
Operational meaning: RTC_E_PROFILE_NO_USER_URI
When RTC returns this result, the relevant contract is creating or enabling an XML profile that defines user identity, servers, transports, authentication, and supported session types, and it says that the provisioning profile omits the required user uri field.
This result carries 0x80EE0033 in the RTC interface facility 0xEE; store the result value at the first RTC callback or method boundary, before retry logic replaces it with a broader timeout or connection message.
Collect enough state to parse the profile with schema-aware diagnostics and identify the owning provision, user, server, or session element; the result evidence should demonstrate why a missing field differs from a present field whose value or cross-field combination is invalid.
Verification workflow
- At the source of this result, preserve the HRESULT, method or callback, timestamp, thread/task correlation, and object generation.
- reconstruct the immediately preceding RTC transition instead of beginning with the later disconnect or UI notification.
- use protocol and object evidence to parse the profile with schema-aware diagnostics and identify the owning provision, user, server, or session element.
- confirm the distinction that a missing field differs from a present field whose value or cross-field combination is invalid.
- create a fresh operation generation after you supply the authoritative user uri value and regenerate the profile rather than inserting a guessed placeholder, and compare its final state with the failing run.
A SIP capture without RTC callback state cannot show which local object accepted or rejected the transition; for this HRESULT, an HRESULT-only log has the opposite weakness: it cannot show whether the result was generated before transmission or mapped from the peer.
Protocol and object boundary
| RTC area | RTC provisioning profile validation boundary |
|---|---|
| Condition to prove | the provisioning profile omits the required user uri field |
| Objects to correlate | profile XML, provision/user/server/session elements, registrar and proxy roles, transport and authentication method |
| Safe corrective direction | supply the authoritative user uri value and regenerate the profile rather than inserting a guessed placeholder |
Two RTC rules frame this result: first, CreateProfile validates the provisioning schema and cross-field constraints; a field can be present yet still be unusable with the chosen transport or role; second, for this HRESULT, The enabled profile selected for a call must support both the destination and the requested session type.
Signals worth preserving
Capture the first result before retry, reconnect, profile re-enable, or teardown changes the evidence; associate it with one RTC object generation and one transaction or media transition.
- Code-specific proof for this HRESULT: parse the profile with schema-aware diagnostics and identify the owning provision, user, server, or session element.
- Correlation key for this HRESULT: redacted profile
XMLpath/version. - Protocol or object snapshot for this HRESULT: user URI and profile key hash.
- Last completed transition for this HRESULT: server role/address/transport.
- Expected output for this HRESULT: authentication method.
For privacy-safe analysis of it, preserve protocol structure rather than payload content; for this HRESULT, authentication values, complete addresses, buddy lists, and bodies should be redacted or hashed under policy.
Recovery and control flow
Recovery from it should be narrow: supply the authoritative user uri value and regenerate the profile rather than inserting a guessed placeholder; while handling it, do not let a higher layer simultaneously recreate the same session, registration, listener, or profile.
Distinguish local rejection from an operation that may already have reached the server; for this HRESULT, use transaction identifiers and final events before replaying any non-idempotent action.
Example for this HRESULT: A provisioning template creates a profile without user uri and RTC rejects it before the profile can be enabled.
Actions that do not address this condition
- The following shortcut is unsafe for this HRESULT: do not log passwords or provisioning secrets from profile XML.
- Another non-solution for this HRESULT is to do not insert placeholder values solely to pass schema validation.
- Keep it intact through exception and UI layers; a generic parameter or network message is insufficient for diagnosis.
Do not confuse it with
It should not be grouped with every value from the same facility. It is tied to the condition “the provisioning profile omits the required user uri field”; preserve that producing boundary before choosing recovery; the result table shows nearby alternatives.
RTC_E_PROFILE_NO_NAME | the provisioning profile omits the required name field |
|---|---|
RTC_E_PROFILE_MULTIPLE_REGISTRARS | the profile defines more than one registrar server where RTC requires one unambiguous registrar |
RTC_E_PROFILE_INVALID_SERVER_ROLE | the profile contains an invalid server role value or combination |
The comparison prevents it from being flattened into a subsystem-wide error bucket with unsafe generic remediation.
Verification after a fix
Verify the result fix with a minimal deterministic case that reaches “the provisioning profile omits the required user uri field”; the failing the case must assert the HRESULT and post-failure state; the passing case should alter one input and confirm both protocol outcome and cleanup.
