PEER_E_INVALID_CREDENTIAL_INFO
Where the peer stack rejects the operation
PEER_E_INVALID_CREDENTIAL_INFO — HRESULT 0x80632081 marks the PEER_CREDENTIAL_INFO supplied for membership issuance contains invalid role, lifetime or identity data. Treat it as a group membership result rather than a generic peer-networking failure.
Peer Grouping layers membership credentials, roles, record signing and encrypted connections on top of graphing and PNRP. Local open state, online connection state and authorization state are separate.
Evidence to preserve before retrying
- Record the first failing surface among PeerGroupIssueCredentials and PEER_CREDENTIAL_INFO.
- Preserve credential structure fields, issuer identity, subject identity, roles, validity interval, flags and existing GMC chain.
- Place successful creation or discovery, state-changing events and the failing call on one timeline.
- Keep peer names, identities, record identifiers, invitation data and endpoints in their original Unicode or binary representation.
Controlled isolation
Issue credentials using the existing member information or a minimal documented credential structure, then add optional fields individually. Change one variable only; simultaneous changes to identity, cloud, database and firewall state destroy attribution.
| Checkpoint | Question for this HRESULT |
|---|---|
| Before the API | Was the required GMC trust chain obtained in this process and user context? |
| At the HRESULT | Preserve credential structure fields, issuer identity, subject identity, roles, validity interval, flags and existing GMC chain. |
| After correction | repair the credential-info structure and verify issuer authority before generating a new invitation or GMC. |
Neighboring result
PEER_E_INVALID_CREDENTIAL differs because credential-info rejects the issuance input structure; invalid-credential rejects a credential or invitation used to join. Keep both HRESULT values in chronological order because a corrected prerequisite can expose the next validation stage.
Safe response
Repair the credential-info structure and verify issuer authority before generating a new invitation or GMC. Preserve durable graph databases, group exports, identity certificates and invitation artifacts before changing them.
