panic: runtime error: invalid memory address or nil pointer dereference about blockchain_go

[fedeonline]

It seems that you're trying to send money from a nonexistent address.
Try blockchain_go listaddresses to se available addresses in current node's wallet.

You may try to change Wallets.go to check if requested address exists in the wallet and raise error if not found.

// GetWallet returns a Wallet by its address
func (ws Wallets) GetWallet(address string) Wallet {
	wallet := ws.Wallets[address]
	if wallet == nil {
		log.Panic("ERROR: Address not found in your wallet")
	}
	return *wallet
}
