During the create public key credential flow, this is thrown when an authenticator response exception contains a read_only_err from the fido spec, indicating a mutating operation was attempted in a "readonly" transaction. The fido spec can be found[here](https://webidl.spec.whatwg.org/#idl-DOMException-error-names).
