Jamo,
thanks for your response, it helped me to probably find cause of this issue. Issue is that set-field action deserializer in single layer serialization is not skipping padding at end of set-field action, so then it have some left-over zeros, and based on logs it then tries to deserialize OutputAction (what type is 0) but body does not match, so it fails. I will try to make fix for this as soon as possible. But until then, with single-layer-serialization disabled it will work.

I do notice in a test I did that the IOBE comes every ~3s which I think is our default polling of operational. anyway, I *think* narrowed down the exact test case that introduces this, and then compared the flow table before and after that test case. The only difference are these two flows: cookie=0x8000006, duration=0.810s, table=21, n_packets=0, n_bytes=0, priority=10,ip,metadata=0x30d52/0xfffffe actions=goto_table:26 cookie=0x8000006, duration=0.810s, table=26, n_packets=0, n_bytes=0, priority=5,ip,metadata=0x30d52/0xfffffe actions=set_field:0x186a9->tun_id,group:225003 full flow table here [0] I am only able to check these things with our CSIT stuff. I tried to manually create a flow that looks like the table=26 flow above (via NB rest) but couldn't figure it out. I think my trouble was trying to give a mask to the metadata. Anything help? I didn't try with serialization disabled yet, as that is gonna take some time to figure out how to toggle it with our CSIT.
