I have our main dashboard. it's customized but is built on an out of the box one using out of the box reports. As of about 2 days ago, the ability to VIEW UNDERLYING DATA fails and gives the below error. 

I also manually pull over 2 tables from SDP and have reports tied to them in the same dashboard. They still function and the underlying data shows normally. I sent in the support logs yesterday on the same issues.

Please advise.
