Upstream description:

After nftables was updated to 1.1.4 on my system, I got the following error when trying to restart a podman container:

Error: netavark: nftables error: got invalid json: data did not match any variant of untagged enum NfObject at line 1 column 5375

#942 suggests it's a JSON schema change in nftables, so here's the info that was requested in that issue:

> # uname -a
Linux potados 6.12.41-1-lts #1 SMP PREEMPT_DYNAMIC Fri, 01 Aug 2025 20:42:03 +0000 x86_64 GNU/Linux

nft --json list ruleset

nftables-1.1.3.json nftables-1.1.4.json

For now I'm working around it by downgrading to nftables 1.1.3.
