I'm having the same issue on mainnet:

goroutine 259 [running]:
github.com/btcsuite/btcwallet/wallet.(*Wallet).handleChainNotifications(0xc00003e140)
/go/pkg/mod/github.com/btcsuite/[email protected]/wallet/chainntfns.go:117 +0x13fb
created by github.com/btcsuite/btcwallet/wallet.(*Wallet).SynchronizeRPC
/go/pkg/mod/github.com/btcsuite/[email protected]/wallet/wallet.go:201 +0x1cb

Edit:

Using LND 12.1 beta, backend is latest neutrino master on bitcoin mainnet

@jacohend can you confirm whether it panicked with the same error message json: cannot unmarshal object into Go value of type string? This error message should not be possible with the neutrino backend as there's no JSON RPC server.

@tivizi do you still see this issue with the latest version? This should've been fixed as of btcsuite/btcd#1577, but the dependency wasn't updated until recently.

[jacohend]

@wpaulino different error string, but same trace. The log view was purged before I copied the specific error string, but it was some issue with timing out during block retrieval. Around the same time the number of good cf-serving peers went to 0.

[tivizi]

@wpaulino ok, i'll try again later. ^0^

[wpaulino]

@jacohend if you're able to reproduce this again, please open a new issue with as much detail as possible (logs, panic stacktrace, etc.).
