Unable to follow @bsky.brid.gy@bsky.brid.gy user

[TomCasavant]

Attempted to follow @bsky.brid.gy@bsky.brid.gy but it couldn't find the webfinger address for the exact same reasons as in #185
Made the suggested change to drop the '/' from the webfinger URL which allowed it to find the inbox
I removed the '.json' from the inbox because I was getting this error:

https://bsky.brid.gy/.well-known/webfinger?resource=acct:bsky.brid.gy@bsky.brid.gy
Profile URL
https://bsky.brid.gy/bsky.brid.gy
{ error: "Couldn't resolve bsky.brid.gy.json as a atproto handle" }

Which was successful, but then I received this error from the brid.gy server:

Sent message to an inbox at bsky.brid.gy!

Response Status Code: 401

Response body: {

  "error": "Couldn't load https://tomcasavant.glitch.me/u/tom to verify signature"

}

I'm not sure if it's something we're missing on our end to point it to the signature or if it's an issue with the brid.gy server (https://github.com/snarfed/bridgy-fed)

@TomCasavant when I fetch https://tomcasavant.glitch.me/u/tom with AS2 conneg, it returns Content-Type: application/json; charset=utf-8. That needs to be application/activity+json or application/ld+json; profile="https://www.w3.org/ns/activitystreams" for ActivityPub to work. https://www.w3.org/TR/activitypub/#server-to-server-interactions

Awesome, thanks! Just from testing it quickly I seem to be getting some 500 errors from bridgy-fed but it's probably something I messed up, I'll look into it this weekend

[snarfed]

Welcome! And 500s are always the server's fault; even if you're doing something wrong, it should return 4xx etc. I'm working through lots of BF bugs right now, hopefully I'll fix yours soon.

Useful, thanks @snarfed - I've patched user.js in my forked copy of Postmarks to set this content type correctly now.

[TomCasavant]

I was looking into this again this morning, @snarfed made the error log a little more specific: we were getting 'id (guid letters and numbers) is not owned by activitypub'

the issue ended up being in the createFollowMessage id

postmarks/src/activitypub.js

Line 147 in 58d1ca1

id: guid,

We should be passing along the full guid url like we are in our other messages:
id: `https://${domain}/m/${guid}`,

This fixed it https://fed.brid.gy/ap/@tom@tomcasavant.glitch.me

Something went wrong and @bsky.bridgy@bsky.bridgy wasn't added to my list of followers though (we must have sent an accept message because bridgy-fed says it followed the account). So I haven't actually managed to test if posts are going through yet

I was trying to trigger an unfollow so I could try getting bridgy-fed to follow the account again but I think something's broken with our 'Undo follow' setup, I can't seem to unfollow anyone (tried a couple of mastodon accounts), it removes it from our side but from mastodon's side it still says we're following them

Still, that's a bit of progress

[TomCasavant]

Manually added bsky.brid.gy as a follower so it could send the create activity...and it worked!

Edit: I think the failure to add the account to my list of followers might have been something I did while experimenting w/ it

But the Unfollow issue is still there (though I see that was already marked as an issue #72 )

[TomCasavant]

Working on a pull request for this fix, and that "failure to add the account to my list of followers might have been something I did" is actually because postmarks isn't seeing the Accept Follow anywhere so it doesn't get added to the list of followers- so I'll have to keep looking at that

[TomCasavant]

Figured it out, the express.json configuration didn't have application/ld+json. PR incoming
