It looks like the name which you can provide in the CLI during publishement of a module isn't the module name, it's the database name. Also in the docs there were some examples which used variables like "DB_NAME" for input of with_module_name / withModuleName for client connections and more. I've created a PR changing the docs so that they mention "database" name instead of "module" name (clockworklabs/spacetime-docs@6ea415a), but the CLI as well as the client SDKs (and possibly the server module library) need changes accordingly.
