I am trying to get all boards by calling "rest/agile/1.0/board/" using javascript routine from another application but I always got 401 Authorization Required and "Reason: CORS preflight channel did not succeed", I use Basic authentication method, but when I call rest/api/2/issue/ from the same javascript routine and same application and same authentication method it works good,
the user I used for basic authentication has "JIRA Software" applicationRoles
could you please tell me what is missing?
