Calling wakuext_peers causes a nil pointer reference

[jakubgs]

I'm trying to run status-go node with Waku v2 for the new Gorush notification fleet:

• https://github.com/status-im/infra-push-notify/issues/1

But I'm getting no peers, and when I try to use wakuext_peers it just crashes:

[email protected]:~ % /docker/status-go/rpc.sh wakuext_peers
{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32000,
    "message": "method handler crashed"
  }
}

And in the logs I get:

ERROR[01-18|12:57:04.306] RPC method wakuext_peers crashed: runtime error: invalid memory address or nil pointer dereference

@jakubgs I think messenger either hasn't started yet, or wasn't started at all (the panic should be probably fixed), but can you check if you waited either long enough (30 seconds should do, just to make sure), or whether StartMessenger was run?

[jakubgs]

Same thing.
