Discovery via Mastodon does not work

[acka47]

Reported by @raphlap via Mastodon DM.

E.g. looking up and following a subject on Mastodon like shown in the SWIB19 presentation does not work. Is there something wrong with the webfinger setup?

[acka47]

Webfinger lookup seems to work, here is how to do it:

1. Get the hex-encoded preferredUsername from https://skohub.io/hbz/vocabs-edu/heads/master/w3id.org/class/esc/n06.jsonas (The .jsonas document contains the ActivityStreams description of a concept as ActivityPub actor)
2. Lookup the resource like this: https://skohub.io/.well-known/webfinger?resource=acct:2f68627a2f766f636162732d6564752f68656164732f6d6173746572773369642e6f72672f636c6173732f6573632f6e3036@skohub.io

A result comes back there but I can see an error in the href URL which looks like this: https://skohub.io//hbz/vocabs-edu/heads/masterw3id.org/class/esc/n06. There is one slash too many after .io and a slash missing after /master. I guess this is the reason for our problem.

The code that creates this link is here, I think:

https://github.com/hbz/skohub-pubsub/blob/aeb6ba5911605268b4a3b54073ddbdbee192fbe6/src/activitypub.js#L70

The error is already in the hex encoded user name, the slash after master is already missing here:

Buffer.from("2f68627a2f766f636162732d6564752f68656164732f6d6173746572773369642e6f72672f636c6173732f6573632f6e3036", "hex").toString()
'/hbz/vocabs-edu/heads/masterw3id.org/class/esc/n06'

Also, the additional slash is already present in the hex string. The .jsonas document containing that string is generated here: https://github.com/hbz/skohub-vocabs/blob/master/gatsby-node.js#L113

Tried many things:

• apache configs come to the mind first, but couldn't come up with anything
• not able to debug test-server because of Webhook on test server fails: "too many open file"  skohub-vocabs#82 et al.
• Fiddled a bit with ACTOR=https://skohub.io{+path} from the .env but think it cannot be solved by it.

Lost, atm.

Issue is fixed. @raphlap give it another try!

I reopen this issue because all other vocabs must we build again to be fixed. See a list at skohub-io/skohub.io#10 .
