This is not something that is because of Indicium (so changing the "allowed origins” won't have effect).
This is because your dashboard uri (https://dashboard.esm.app.br/) returns the X-Frame-Options
header. The browser tries to load the url you provided for the previewer/iframe and blocks it because of this header.
Hi @Dick van den Brink,
Thanks for the tip.. I was able to do an override via the config to not set this header.. but however it still doesn't load, don't get the blocked message anymore, but the previewer stays empty.
<iframe data-testid="previewer__custom-screen-url" src="https://dashboard.esm.app.br/superset/dashboard/p/lr87LblDQkE/" sandbox="allow-scripts allow-same-origin allow-popups allow-popups-to-escape-sandbox" class="css-y1obzt"></iframe>
Any suggestions no how to troubleshoot this?
