Returns the history entries kept for this run, under contactAutomationLogs. For most runs this is not the full step history: only some kinds of steps, such as waits, goals and sends, keep an entry here. For the full step history, use GET /automations/{seriesId}/contactAutomations/{contactAutomationId}/steps. The list is not paged. The order is not guaranteed. Returns 404 if the run does not exist.
