Review comment:
       I think druid query ids are normally UUID v4 by convention. it would be 
best to stick to that. Use an off the shelf uuid v4 library like 
https://www.npmjs.com/package/uuid instead on hand rolling a random number 
generator here.

Review comment:
       no need to call `QueryView.isJsonLike(queryString)` twice in 3 lines, 
call it once up top and then reuse the variable

Review comment:
       will `void` here be enough to make sure nothing complains about an 
unhandled promise rejection (we do not want to trigger 
https://developer.mozilla.org/en-US/docs/Web/API/Window/unhandledrejection_event)?
 Can you try this when it fails? Does the error get fully ignored or is there a 
need for `.catch(() => {})` ? If I was in your place I would add the `.catch(() 
=> {})` just to be sure (and to save time on doing the proper research)

Review comment:
       where are you setting the `context.queryId` if this is not a SQL query?
