To get the timeline for question I am sending this request:

[https://api.stackexchange.com/2.2/questions/63299112/timeline?site=stackoverflow&fromdate=1597649222][1]

I am getting empty results:
````
{"items":[],"has_more":false,"quota_max":300,"quota_remaining":270}
````

However query to fetch complete results without timeline has all the records:
