I've then used dashboard actions to incorporate Tableau data into my HTML/JS. It all works fine on my desktop but now when I upload it to Tableau Server, I get error: "A potentially unsafe URL has been blocked"
I've found this kb article about whit listing but I'm not entirely sure what value to pass in.
Thanks for the help!
From peeking at the source code, it looks like adding "data" to the whitelist should work.
tabadmin set vizqlserver.url_scheme_whitelist data
