ah yeah the help message is from the Cosmos SDK which doesn't enforce a chain-id format. We can update the help message to require the chain-id and also the error message to be more descriptive

@fedekunze isn't it possible to make it generate a compatible chain-id by default?

[fedekunze]

you can but it needs to have the format <chain_name>-<chain_id>

[helder-moreira]

It would basically require replacing this with a copy of the InitCmd with this line adapted to the right format. Am I right? Would you welcome a PR for that?

EDIT: or maybe just another wrapper on the command to generate the chain-id.
