Hi there, I am currently facing the same issue. It appears that running with the log level set to debug yields an additional line, but nothing of interest.
Setup code I used
The same logic used to work with previous versions of the libp2p infrastructure (see peerchat for an example). It seems that, for some reason the
peerSourcefunction is holding nil whenfindPeersis called.There was a recent discussion on the libp2p forums featuring the same error, I’ll leave this here in case it is related: https://discuss.libp2p.io/t/minimal-example-for-autonat-autorelay-with-pnet/1589. Even though there has been a huge improvement in the quality of the available documentation, I could not find a minimal example with AutoRelay, which would probably help a lot in this case.
