Why does this error occur? Normally it isn't that big of a deal, but I just spent the last 10 mins creating color rules and now I am going to lose all of them and have to start all over…
Are you currently logged into your instance? If not try and log into your instance again in another tab and then try and save it again.
No and it just happened again to me!!!
I was signed in. I think the issue was I had some colors for fields (from prior dataset of the card) that were still in there and preventing me from saving.
