"Incorrect prefix for did:key" in verifyJwt

[CodePanter]

Hello! I've worked through the 'getting started' and 'automated labeling' documentation pages, and am stuck on this error. I feel it might have something to do with the reverse proxy step; as I had some issues getting Caddy to work, but it appears to be running, so don't know where to go from here.

As soon as anyone likes a role post, I get the following error saying the event can't be emited due to XRPC not being supported. I'd appreciate any help I can get 👍

You seem to have a catch-all on your labeler domain — see for example https://osrslabeler.pant.re/xrpc/com.atproto.label.queryLabels?uripatterns=* vs. the same route for mod.bsky.app

[CodePanter]

You are right, that was an easy fix. I am once again stuck though; the 'XRPCError: InternalServerError > Internal Server Error' isnt telling me much, and I can't quite figure out what "Incorrect prefix for did:key:zQ3shpqC5YncxbXYQRusDfdSqbSgbc1nxGntrirz5K2b1tioy'" means either. My apologies if I'm doing something silly; but your help is very much appreciated!

Weird, I'll see if I can reproduce.

Thank you! I've tried different versions of your package, including the newest beta. You can find the code as my most recent repository on my profile.

Fixed in 0.1.12!

[CodePanter]

Thank you! The incorrect prefix error is indeed fixed now, however now I get a 'invalid curve for multikey' error:

I was in the middle of debugging this. I had gotten as far as spotting this typo, but I was nowhere near fixing everything else! https://github.com/skyware-js/labeler/blob/a9ce6c9855dcde242a690e1756d52fe1ce0643d0/src/util/crypto.ts#L316
