Description

How to resolve this error and download the video from hotstar?

[merval]

Interesting, when pulling the content for that link, the 'contentId' youtube-dl is calling out is listed under a section called "legacy_details", so the value returned as "video_data" is None, which throws a KeyError.

youtube-dl/youtube_dl/extractor/hotstar.py

Lines 110 to 116 in f5863a3

	for v in app_state.values():
	content = try_get(v, getters, dict)
	if content and content.get('contentId') == video_id:
	video_data = content
	break
	title = video_data['title']

There are three items in app_state.values() on line 110, the first is the one we want and the other two are None. But because of the nested 'contentId', we can't find it.
Here is the json output of the content for the link 'https://www.hotstar.com/in/tv/aame-katha/1260013166/maheswaris-smart-move/1100040237'
It should be noted the video_id called out is '1260013166' which is nested under the 'legacy_details', however the 'contentId' at the parent level is '1100040237', both of which are listed in the URL above at different places.
EDIT: the Key name likely changed from 'contentId' to 'showContentId' since the video_id is listed there too.
