TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

Hi, there, thanks so much for this starter. I'm getting a build error on the sitemap plugin and cannot pinpoint a fix. It will build successfully when I remove the plugin from my gridsome.config.js file, but when I add it back in, I get this error.

I haven't found a solution pertaining to Gridsome on this error. Just React.

Any suggestions on how to troubleshoot this would be greatly appreciated.

Thanks so much and thank you again for putting this together. It's been really great for me to learn. Thanks.
