gatsby-plugin-feed is showing my home page and about page as recent updates

[joseph-allen]

If I go on my website ortom.ai with an RSS reader, all blog posts show up correctly, but for some reason, my home page and the about page on my website show up as new posts from the point I land on my site.

They seem to be collecting the data from the pages index.md files even though these are not rendered in the page itself.

My assumption was that match: '^/journal/', would have meant my RSS feed only scraped my blog pages, but content from my case studies page is also showing up. http://localhost:8000/caseStudies

My configuration is listed below:

resolve: 'gatsby-plugin-feed',
      options: {
        query: `
          {
            site {
              siteMetadata {
                title
                description
                siteUrl
                site_url: siteUrl
              }
            }
          }
        `,
        feeds: [
          {
            serialize: ({ query: { site, allMarkdownRemark } }) => allMarkdownRemark.edges.map((edge) => ({
              ...edge.node.frontmatter,
              description: edge.node.excerpt,
              date: edge.node.frontmatter.date,
              url: site.siteMetadata.siteUrl + edge.node.fields.slug,
              guid: site.siteMetadata.siteUrl + edge.node.fields.slug,
              custom_elements: [{ 'content:encoded': edge.node.html }],
            })),
            query: `
              {
                allMarkdownRemark(
                  sort: { order: DESC, fields: [frontmatter___date] },
                ) {
                  edges {
                    node {
                      excerpt
                      html
                      fields { slug }
                      frontmatter {
                        title
                        date
                      }
                    }
                  }
                }
              }
            `,
            output: '/rss.xml',
            title: 'Ortom RSS Feed',
            // optional configuration to insert feed reference in pages:
            // if `string` is used, it will be used to create RegExp and then test if pathname of
            // current page satisfied this regular expression;
            // if not provided or `undefined`, all pages will have feed reference inserted
            match: '^/journal/',
            // optional configuration to specify external rss feed, such as feedburner
            link: 'https://ortom.ai/RSS.xml',
          },

I think I've fixed this by adding a filter to my GraphQL, I figured I would post here as I couldn't find this solution through googling.

                allMarkdownRemark(
                  filter: {fileAbsolutePath: {regex: "/(journal)/"  }},
                  sort: { order: DESC, fields: [frontmatter___date] },
                ) {
