Hi,
First, please try '--verbose' option of ryu-manager to get the detail logs.
On my environment, the following error messages were shown.
$ ryu-manager ryu.app.simple_switch_13 --verbose

And, to use the SET_FIELD action, the OXM prerequisites (see 7.2.3.6 in
OpenFlow Spec 1.3)
corresponding to the field to be set must be included in the flow entry.
For example, to set ip_dscp by the SET_FIELD action, eth_type=0x0800 or
eth_type=0x86dd is
required in the match field.
