Hi, a follow-up on this, plus something I should have flagged when I opened it: #69645 targets the same issue (#68317) and came first, so a maintainer should decide which one to take. The difference is scope. #69645 says `db downgrade` doesn't rewrite metadata rows "into an older serialization format" in general. This PR narrows that to `trigger.kwargs`, because `ExtendedJSON` (behind `dag_run.conf`, `taskmap`, etc.) uses `BaseSerialization` in both 3.1.8 and 3.2.1 (source quoted in the description). This PR also names the symptom users will actually see (`KeyError: <Encoding.VAR: '__var'>`). #69645 also adds a warning to `usage-cli.rst`, which this PR deliberately doesn't. If you'd rather merge #69645, I'm happy to close this one and move the source analysis to a review comment there so its wording can be tightened. Either way, the CI runs here show as failed with no jobs executed, so they look like they need workflow approval. -- This is an automated message from the Apache Git Service.
