## InvalidDPoPProofError Class

Subtype of [OidcError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.OidcError 'Abblix\.Oidc\.Server\.Common\.OidcError') tagging an RFC 9449 §7\.1 DPoP proof rejection at a
protected endpoint \(UserInfo, introspection, revocation\)\. The typed marker lets the
response formatter pattern\-match deterministically and emit the
`WWW-Authenticate: DPoP error="invalid_dpop_proof"` challenge instead of a Bearer
challenge, without string\-comparing the error code\. Mirrors [UseDPoPNonceError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.UseDPoPNonceError 'Abblix\.Oidc\.Server\.Common\.UseDPoPNonceError')\.

```csharp
public sealed record InvalidDPoPProofError : Abblix.Oidc.Server.Common.OidcError, System.IEquatable<Abblix.Oidc.Server.Common.InvalidDPoPProofError>
