Trigger execution from webui don't display the execution when some lag 
When we create the execution from the webui, the execution is created and return directly. 
But the indexer could not have the time to index the execution on the backend. 
This lead by a 404 on `/api/v1/executions/{{executionId}}` and the ui freeze here.

Difficult use case here, I think the better will be to use only the execution return during the creation and reach the updated information from the listen url (without trying to reach the url below). 
This will lead to no dependency on indexer on this part of the webui.
