Adding HTTP Headers to Plugin in Development

Maybe I need to set up this ENV?

  if env['REQUEST_METHOD'] == ('OPTIONS') && env['HTTP_ACCESS_CONTROL_REQUEST_METHOD']
    return [200, Discourse::Cors.apply_headers(cors_origins, env, {}), []]
  end

Do I need to set some ENV vars? If so, where? Maybe this is my failure?

Thanks!

FWIW, set this in the plugin initializer:

Discourse.SiteSettings.discourse_enable_cors = true;
Discourse.SiteSettings.discourse_cors_origin = "*";

and console.log shows these setting are OK… but the dreaded access denied remain in the console as well :frowning:
