This is thrown when the create public key credential operation failed with no more detailed information. This could be something such as out of memory or some other transient reason - either from fido directly or through the public key credential flow in general. The fido spec can be found[here](https://webidl.spec.whatwg.org/#idl-DOMException-error-names).
