For example, "\[AIRFLOW-XXX\] My Airflow PR" - https://issues.apache.org/jira/browse/AIRFLOW-3887 - In case you are fixing a typo in the documentation you can prepend your commit with \[AIRFLOW-XXX\], code changes always need a Jira issue. ### Description - [ X ] Here are some details about my PR, including screenshots of any UI changes: dagre-d3 v0.6.3 has a bug that causes this Javascript error when loading the Graph View: TypeError: previousPaths.merge is not a function The bug fix [1] has been merged to master, but hasn't been released to npm yet. This change temporarily downgrades our version of dagre-d3 until dagre-d3 v0.6.4 is released [2] I also fixed a bug I encountered in the `compile_assets.sh` where the script would fail if the directory `airflow/www/static/dist/` exists but is empty.
