o​sa_k It shows up only after I manually ran `curl -X POST -i -d source=https://ap.brid.gy/convert/web/https://social.mikutter.hachune.net/users/osa_k/statuses/110841748303822746 -d target=https://osak.jp/posts/ja/breath-of-the-wild/ https://webmention.io/osak.jp/webmention`. I don't know the exact source URL Bridgy Fed would use, but the reply wasn't automatically synced

o​sa_k Here's the log link corresponding to that reply https://fed.brid.gy/log?path=%2F_ah%2Fqueue%2Fwebmention%2C%2Finbox&start_time=1691310860&key=https%3A%2F%2Fsocial.mikutter.hachune.net%2Fusers%2Fosa_k%2Fstatuses%2F110841748303822746%2Factivity
#
o​sa_k It barely shows a log message about searching for log messages then reporting no logs found 🤔
#
o​sa_k also, more or less, the other reply to the article isn't synced to webmention.io (I didn't change any configs between two replies) https://social.mikutter.hachune.net/@osa_k/110841715843010389
#
gRegor Hm, not sure. [snarfed] can probably look into the logs more

#
[snarfed] hi again osa_k! you're right about those Bridgy Fed URLs and the redirects. wm receivers are supposed to follow source URL redirects, and I'm pretty sure http://webmention.io has done that for a long time now
#
[snarfed] here's the http://webmention.io status URL for the webmention: https://webmention.io/osak.jp/webmention/TKyZd7obVjsldG90Na5v . it says the source doc doesn't link to the target. but fetching https://ap.brid.gy/convert/web/https:/social.mikutter.hachune.net/users/osa_k/statuses/110841748303822746/activity (and following redirects), it definitely does. so I'm not sure what happened

#
o​sa_k Hey snarfed, thanks for the response! I looked into the code a bit further and started to suspect that webmention.io doesn't handle redirects in reality.
#
o​sa_k So far as I can tell webmention.io seems to delegate microformat parsing to xray.p3k.io (https://github.com/aaronpk/webmention.io/blob/main/helpers/xray.rb#L10). But if I pass the ap.brid.gy URL, it isn't following redirect http://xray.p3k.io/parse?url=https%3A%2F%2Fap.brid.gy%2Fconvert%2Fweb%2Fhttps%3A%2Fsocial.mikutter.hachune.net%2Fusers%2Fosa_k%2Fstatuses%2F110841748303822746%2Factivity&pretty=true
#
o​sa_k hmm, that XRay service is disabling redirect following for `brid.gy` links 🤔 https://github.com/aaronpk/XRay/blob/main/lib/helpers.php#L44
#
o​sa_k [snarfed], do you know any context by any chance? The webmention.io-XRay stack doesn't seem to expect Bridgy to return redirects
#
[snarfed] Oh wow, that seems wrong. cc [aaronpk]
#
aaronpk I didn't think I had any special logic for bridgy in there...
#
aaronpk Huh
#
aaronpk That was apparently added 8 years ago
#
aaronpk i vaguely remember some old issue with appspot URLs that I had to work around
#
[snarfed] We were all young and foolish
#
[snarfed] Funny, skimming the first page of https://github.com/aaronpk/webmention.io/issues, I suspect this is the root cause of many of them
#
[snarfed] osa_k++ awesome sleuthing!

o​sa_k whoa, didn't imagine my adventure results in such a big found! Thanks [snarfed] 🙂
