I have copy and pasted the command to my c-lighting node and it works producing the following output:

lightning-cli invoice 100 invoice20190126 payme

}

Which version of c-lightning are you using? Also there was recently a change of the JSON RPC API due to the new plugin system. Could it be that you have not updated lightning-cli but only lightningd?

I use docker-compose and don't see the version there. I have stopped, removed the container and rebuild clightning_bitcoin. Now it is working! Thanks! The respond is:
