Hi there, and sorry this has gone quiet for so long. We're no longer supporting Superset 2.x or prior, and since it's been a while since this thread saw any activity (around 6 months), I'll close this as stale. If it is still an issue in Superset 3.x or newer, we can re-open this, or feel free to open a new issue with updated context. Thanks!
