"<%- configName %>" is invalid syntax for a config specifier. * If your intention is to extend from a configuration exported from the plugin, add the configuration name after a slash: e.g. "<%- configName %>/myConfig". * If this is the name of a shareable config instead of a plugin, remove the "plugin:" prefix: i.e. "<%- configName.slice("plugin:".length) %>". "<%- configName %>" was referenced from the config file in "<%- importerName %>". If you still can't figure out the problem, please stop by https://eslint.org/chat/help to chat with the team.
