New issue 1680: Federation error parameter operation is underspecified
https://bitbucket.org/openid/connect/issues/1680/federation-error-parameter-operation-is

Michael Jones:

The generic error response at [https://openid.net/specs/openid-connect-federation-1\_0-23.html#name-generic-error-response](https://openid.net/specs/openid-connect-federation-1_0-23.html#name-generic-error-response) includes an `operation` parameter that is not present in OAuth errors.  There’s one example in the spec where the `operation` value is  `resolve` but no other values for other operations are specified.

We should do one of two things:  delete the `operation` parameter, since the operation is already known in the context of the request that the error is in response to, or specify the `operation` values for all operations.

I’m in favor of simply deleting it - aligning with the OAuth error format.
