Unclear why. Together with #1653, this means there's no mean to get inbox URL.

[saschanaz]

Interestingly, fetching https://bsky.brid.gy/r/https://bsky.app/profile/did:plc:xmbyi47sypz7q2mx5j7ay6sl also gives handle-based ID in this case, also without the inbox property.

[snarfed]

Oh wow, interesting. Yeah, we probably shouldn't be serving AS2 actors for paths like these at all.

Out of curiosity, do you know where this fetch came from? Ie, do you know where https://bsky.brid.gy/r/https://bsky.app/profile/sanhwa-lee.com or https://bsky.brid.gy/r/https://bsky.app/profile/did:plc:xmbyi47sypz7q2mx5j7ay6sl originally appeared as ActivityPub-fetchable ids?

[saschanaz]

It didn't appear really, I wanted to follow this user (saw in bsky) and that didn't work so I started debugging 😄

[snarfed]

Ah ok, thanks for the explanation. That user hasn't enabled the bridge, so you can't follow them from the fediverse yet. Congrats on finding an unusual way to convert part of their profile to AS2 though! Similar to https://granary.io/ , I guess.

I'll keep this issue open to track turning that off.

[saschanaz]

I see ap.brid.gy in the followers list though 👀

[snarfed]

OK! They're not actually bridged though: https://fed.brid.gy/bsky/did:plc:xmbyi47sypz7q2mx5j7ay6sl . Maybe they followed ap.brid.gy before their profile was fully set up and satisfied https://fed.brid.gy/docs#troubleshooting, or maybe during an outage like #1520. Feel free to ask them to try again!

[saschanaz]

Oh no, so I won't be able to (ab)use the /r/ url to resolve bsky URLs? I find it useful 😢

[snarfed]

Hah, sorry. It'll still work for Bluesky post URLs, if they're bridged! And you can find a bridged Bluesky user by their Webfinger, @[handle]@bsky.brid.gy (https://fed.brid.gy/docs#fediverse-follow-bluesky) or by their AP actor id, https://bsky.brid.gy/ap/[DID].
