Hi, After installing @builder.io/gatsby into a web app using Gatsby I’m getting errors: Cannot read property ‘allBuilderModels’ of undefined 153 | const component = config.templates[modelName]; 154 | invariant(fs.existsSync(component), `@builder.io/gatsby requires a valid template path for each model`); > 155 | let entries = result.data[config.fieldName][modelName]; > | ^ > 156 | offsets[index] = offsets[index] + entries.length; > 157 | > 158 | if (entries.length === config.limit) { File: node\_modules/@builder.io/gatsby/gatsby-node.js:155:30 TypeError: Cannot read property ‘allBuilderModels’ of undefined - gatsby-node.js:155 createPagesAsync [holystones]/[@builder.io]/gatsby/gatsby-node.js:155:30 - gatsby-node.js:135 Object.exports.createPages [holystones]/[@builder.io]/gatsby/gatsby-node.js:135:5 - api-runner-node.js:481 runAPI [holystones]/[gatsby]/src/utils/api-runner-node.js:481:16 info Total nodes: 213, SitePage nodes: 11 (use --verbose for breakdown) failed createPages - 0.146s **Gatsby-config.js** { resolve: ‘@builder.io/gatsby’, options: { publicAPIKey: process.env.publicAPIKey, templates: { MyPage: path.resolve(‘src/templates/MyPage.jsx’) }, }, }, **MyPage.jsx** import React from ‘react’ import { builder, BuilderComponent } from ‘@builder.io/gatsby’ import { graphql } from ‘gatsby’ builder.init(‘6ee7e23aed774a3093b12f1696b8f6ad’) function MyPage (props) { console.log(props.data) const content = props.data?.allBuilderModels.MyPage[0]?.content; return } export const query = graphql` query($path: String!) { allBuilderModels { page( target: { urlPath: $path } limit: 1 options: { cachebust: true } ) { content } } }` export default MyPage How to resolve it?

If you don’t expect “landingPage” to exist on the type “builder” it is most likely a typo. However, if you expect “landingPage” to exist there are a couple of solutions to common problems: - If you added a new data source and/or changed something inside gatsby-node.js/gatsby-config.js, please try a restart of your development server - The field might be accessible in another subfield, please try your query in GraphiQL and use the GraphiQL explorer to see which fields you can query and what shape they have - You want to optionally use your field “landingPage” and right now it is not used anywhere. Therefore Gatsby can’t infer the type and add it to the GraphQL schema. A quick fix is to add at least one entry with that field (“dummy content”) It is recommended to explicitly type your GraphQL schema if you want to use optional fields. This way you don’t have to add the mentioned “dummy content”. Visit our docs to learn how you can define the schema for “builder”: [https://www.gatsbyjs.org/docs/schema-customization/#creating-type-definitions](https://mailtrack.io/trace/link/45f59f6682d2aa25775b8cb1fe561a903bc8a37f?url=https%3A%2F%2Fwww.gatsbyjs.org%2Fdocs%2Fschema-customization%2F%23creating-type-definitions&userId=6435041&signature=2a6304c939d67418) File: node\_modules/@[builder.io/gatsby/gatsby-node.js:140:24](http://builder.io/gatsby/gatsby-node.js:140:24) not finished createPages - 0.228s Thanks. ---

Hi @Voyager this error means that you don’t have model named `landingPage` in your builder space, you can create one on the [models page](https://builder.io/models). ---

In the screenshot I don’t see a model named `landingPage` , I see a `page` model, maybe you meant to use that instead?
