Got an error stack after a successful follow, cannot repro

[mazz]

Got this error stack once, but restarted iex and it didn't happen the second time.

I'm pretty sure this is a legit npub:

iex(4)> NostrApp.follow("npub15tmnw5709va4pgrzpn2kqnnuc2ejssm9a599262jwdpmvmwn9rmqawlkv7")

Here's how I initialized my iex:

.iex.local.exs:

relays = [
  "wss://relay.nostr.bg",
  "wss://relay.nostr.pro"
]

nsec = "nsec...lg"
{:ok, pkey} = NostrBasics.Keys.PrivateKey.from_nsec(nsec)
NostrApp.start_link(relays, pkey)

{:ok, pubkey} = NostrBasics.Keys.PublicKey.from_private_key(pkey)
NostrApp.timeline(pubkey)

from mix.lock:

  "nostr_basics": {:hex, :nostr_basics, "0.1.6", "dbbbef1a16645f6edb1102286d2576907785ef320115ebfd525da18e2c5f596d", [:mix], [{:bech32, "~> 1.0", [hex: :bech32, repo: "hexpm", optional: false]}, {:binary, "~> 0.0.5", [hex: :binary, repo: "hexpm", optional: false]}, {:jason, "~> 1.4", [hex: :jason, repo: "hexpm", optional: false]}, {:k256, "~> 0.0.7", [hex: :k256, repo: "hexpm", optional: false]}], "hexpm", "ac8a4ac54c8956a5f435ddf9a2fe220c2f5e7167cbdca024986eeba0ab3b5377"},

Elixir:

Erlang/OTP 25 [erts-13.1.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]

Elixir 1.14.2 (compiled with Erlang/OTP 25)

[RooSoft]

In the 4th line of iex, it is attempted to follow using an npub...

The solution probably is

{:ok, pubkey} = PublicKey.from_npub("npub15tmnw5709va4pgrzpn2kqnnuc2ejssm9a599262jwdpmvmwn9rmqawlkv7")
NostrApp.follow(pubkey)

This probably is under documented as we speak. Also, an improvement might be that the lib converts npubs automatically, so that 4th line you made might start to make sense.

To be honest, as a user, I'd expect what you did to work. Unfortunately, as we speak, most functions expect a binary version of most stuff, especially keys.

[RooSoft]

Also, the fact that that specific line returns a :ok is pretty odd, as I'm pretty sure it can't work.

Been a while I haven't tinkered with that lib, so, might be that in the past I made some improvements to make it work, but on the top of my head, that's not the case.

Got the same error with a binary pubkey:
