The issue seems to be contained in the error message.

`Could not locate RPC credentials. No authentication cookie could be found, and no rpcpassword is set in the configuration file (/home/lightning/.bitcoin/bitcoin.conf)`

So, set rpcuser and rpcpassword appropriately in `~/.bitcoin/bitcoin.conf`.
