Hi.\ndoes anyone know how to easily debug http 400 in superset ? I got lots of them (anyway superset is working almost ok)\ngot this\n\n```<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">\n&lt;title&gt;400 Bad Request&lt;/title&gt;\n&lt;h1&gt;Bad Request&lt;/h1&gt;\n&lt;p&gt;The CSRF token is missing.&lt;/p&gt;```\n
