Nano-node: Error deserializing config

[hamiltino]

Trying to start the rai_node daemon, i have followed these steps:

./rai_node --daemon
sed -i 's/"rpc_enable": "false"/"rpc_enable": "true"/g' ~/RaiBlocks/config.json
sed -i 's/"enable_control": "false"/"enable_control": "true"/g' ~/RaiBlocks/config.json

Launch rai_node in test mode
./rai_node --daemon

I get the error: "Error deserializing config"

any help appreciated:
