I am trying to create a SQL task in Workflows. I have my query which executes successfully in the SQL editor, and it is saved in a repo.

However, when I try to execute the task, the below error shows.
Query text can not be empty: BAD_REQUEST: Query text can not be empty.

Hovering over the magnify option shows the query blank too. 

Some queries I didn't create do appear though, so I'm not sure what I'm missing.
