Just a thought, I had to update libnftnl as well when updating. I on 1.2.0 so that may be worth checking. Also guess as you know which bit of code is bombing, can you look it up on github, and run the blame script. Then you be able to see who made the change, and that will give someone to contact ...
The patch is now in the master branch, so hopefully the next release will have it fixed.
The problem is particularly with populating the cache that the nft command uses, in particular when zero results are returned. So it's unlikely that the other libraries have any impact.
There are problems with netfilters in the older version, probably wait for the newer version Sir, Also, check again your netfilters config , I think there are some errors with # echo $? BTW, are you sure that your tables,, "filter" and "nat" are well defined?? Good luck
