Returns the first failure without invoking the remaining fetchers\. |
| [RequestObjectFetchAdapter](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.BackChannelAuthentication.RequestFetching.RequestObjectFetchAdapter 'Abblix\.Oidc\.Server\.Endpoints\.BackChannelAuthentication\.RequestFetching\.RequestObjectFetchAdapter') | Adapts the generic [IRequestObjectFetcher](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher 'Abblix\.Oidc\.Server\.Features\.RequestObject\.IRequestObjectFetcher') \(signed\-JWT Request Object handling\) to the CIBA\-specific [IBackChannelAuthenticationRequestFetcher](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.BackChannelAuthentication.RequestFetching.IBackChannelAuthenticationRequestFetcher 'Abblix\.Oidc\.Server\.Endpoints\.BackChannelAuthentication\.RequestFetching\.IBackChannelAuthenticationRequestFetcher') contract, passing the request's `request` parameter through unchanged for JWT validation and parameter merging\. |

The validation pipeline runs against the resolved request, not the raw one\. |
