Gatsby Feeder

I have one person in the world that subscribed to my old Jekyll rss feed and snice moving to Gatsby, I cut off that special baby boy. My oldest friend! What a monster. The problem is that the default Gatsby RSS feed gatsby-plugin-feed uses an out-of-the-box configuration that is not compatible with the starter I had built my site on.

tl;dr make sure your graphQl query matches

Slugs and Paths

I was using path as defined in my frontmatter, but the out of the box config for the gatsby-plugin-feed uses slug as a field to pull the relative path to each blog post for the feed. I also use both portfolio and blog posts so I wanted to include my type frontmatter data designation.

In order to get mine to work, my config is below. I would CMD+F for 'slug' and then make sure that it is using whatever your term and query structure is using. I would also remove this line filter: {frontmatter: { draft: { ne: true } }} unless you are using drafts. I don't use drafts because I always push straight to ,master and then to production on my blog. It's my blog and here, there are no rules.

LAST THING / POSTSCRIPT

I am getting some UTF-8 encoding error at line 3,500 or so of my feed, but its otherwise working. I am not sure what this is or why the error pops up there of all places, from a very early blog post (April 2016).
