Embedded queries failing to load on refresh

Bruno-DaSilva commented 2 years ago

Describe the bug On load of an incident page, queries show as blank. Very occasionally they will render correctly. If you edit the query and save it, it renders correctly until you refresh again.

To Reproduce Steps to reproduce the behavior:

Go to an incident with a created 'query'
Scroll down to the query panel.
Observe that the query panel shows "No data or query"

Expected behavior The query panel shows the saved query as a graph.

I took a look in my dev console to see what's going on. I notice that there are TWO /api/ds/query endpoint requests being sent out - one of them returns results and one of them does not. If the zero-result query fails then the panel renders, if it succeeds then it shows no data.

The two requests are identical except for the payload:
