Access adhoc schema

using SQL Query , i created table (tb1) and ran the query. The output of the query saved data in tb1, and also created link to schema , which had "Random identifier: XXXXXsomenumberXXX" 

I wanted to access this schema, however when i click on it, the page only show blank screen.

I tried accessing using API, however am not able to fetch schema details either using tenant or global as attribute value.
