          tip: A `--config` flag must either be a path to a `.toml` configuration file
               or a TOML `<KEY> = <VALUE>` pair overriding a specific configuration
               option

        The supplied argument is not valid TOML:

        TOML parse error at line 1, column 7

        1 | foo = bar
