Depending on what version of OpenFlow you are using, you should refer to
its spec document. For example the OF1.3 spec is here:
https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.0.pdf
Page 79 defines what error codes and types are associated with. You have
error type 1 and code 8 so this means you are getting an OFPET_BAD_REQUEST
and OFPBRC_BUFFER_UNKNOWN error, which means your "Specified buffer does
not exist".
Hope this helps, I would look at what buffer you are specifying when you
are sending rules to your switch. Ideally Ryu could integrate this type of
error message context into the OFPErrorMsg print outs.
