REST/CLI command will add a schema definition with 'upload' if the given file does not exists

If the CLI command "schema upload -f noFile SchemaName" or PUT like

"curl -X PUT --data-binary @simple.proto http://127.0.0.1:11222/rest/v2/schemas/Simple"

does not point to a valid file the entry is created but will not have a schema and also no error message.
