Cannot read properties of undefined (reading 'createNodeField'), gatsby-node.js:5:47 about gatsby-source-instance-name-for-remark

Take it back. The sourceInstanceName didn't show up in graphiQL, and when I ran build again, the errors re-appeared. Perhaps a version problem? This is a new site, so gatsby 5.7.0, transformer-remark 6.7.0, react 18.2.0. These were the warnings on install (no errors, and these warnings occur on every plugin install, perhaps 5.7.0 is a bit too bleeding edge to be default?):

I realised that allFile.nodes.childMarkdownRemark does the same job without needing a plugin, so it's not important.
