[async] error: component not found for job <id>

[rwspielman]

We are sporadically seeing the error 'component not found for job ' in the dev console when loading dashboards with Global Async turned on. The charts never loads. When searching through the network requests, we can see that the api request to async_event does in fact return the correct job and we can follow the result_url in that api response to the data of the missing chart. It does not make a call to the explore_json/data api for that chart.

Just a shot in the dark: My thoughts are possibly a race condition between loading of the ui components and the return of the api response? It seems to always be the first charts that return from async_result api (and usually in a separate request from the others that do end up loading)

Expected results

Charts to load properly

Actual results

Chart never loads, and error 'component not found for job ' warning in console.

Screenshots

How to reproduce the bug

1. Turn on Global Async
2. Create dashboard/charts

5. may need to refresh a couple of times and wait for a chart to continuously have the spinning loader / the error in the console show up. it is very sporadic
