The 1.10.0 documentation says I should be able to make a POST against /api/experimental/dags//dag_runs to trigger a DAG run, but instead when I do this, I receive an error:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>The browser (or proxy) sent a request that this server could not understand.</p>
To make this work, I figured out that I needed to send an empty JSON string in the body:
curl -X POST \
http://airflow.dyn.fa.disney.com/api/experimental/dags/people_data/dag_runs \
-H 'Cache-Control: no-cache' \
-d '{}'
