Hashtag.from_name(): KeyError: 'graphql'

Found an error given by using wrong json metadata. Tried using different hashtags and to revert to previous versions of Instaloader, but it still gives the problem. I also checked your built-in code and everything looks fine to me, so I suppose it has something to do with Instagram changing it’s metadata format. Maybe this was already fixed for other types of objects but you forgot to fix it for Hashtags (?)

Traceback (most recent call last):

Thanks to you all for sharing your observations and for creating such a beautiful collection of workarounds for this issue!

The download of hashtags should now be fixed in Instaloader’s latest pre-release, Version 4.9b1.

Here’s a snippet that might elucidate #874 with datetime functionality taken from #121 . It takes posts between dates following a hashtag using the NodeIterator code and stores them in a list.

START = datetime(2021, 5, 28)
END = datetime(2021, 5, 30)
HASHTAG = "<Some Hashtag>"
GraphQL_Hash = "<Some GQL hash>"
posts = []

post_iterator = instaloader.NodeIterator(
    L.context, GraphQL_Hash,
    lambda d: d['data']['hashtag']['edge_hashtag_to_media'],
    lambda n: instaloader.Post(L.context, n),
    {'tag_name': HASHTAG},
    f"https://www.instagram.com/explore/tags/{HASHTAG}/"
)
        
def gen(start, end, posts):
    for post in posts:
        if post.date > start and post.date > end:
            pass
        elif post.date >= start and post.date <= end:
            yield post
        elif post.date <= start:
            break

for post in gen(start=START, end=END, posts=post_iterator):
    posts.append(post)

Hope this helps. Edited for formatting.

What is a “GQL hash”? I did it: And the output was this error: Where can i find the GQL hashtag for my “home” hashtag?
