Excited about builder io - it sounds like exactly what we need for both technical and non-technical users. Unfortunately, the visual editor doesn’t work for us! I’ve set up a test project as per github… gatsby-starter-builder, added the sample models, API key, running locally with _gatsby develop_. No changes to the starter project. I can see the site on [builder.io](http://builder.io) where it loads localhost:8000/ into the preview. If I edit some text the preview doesn’t reflect the change, same for adding or removing components. ![image](https://us1.discourse-cdn.com/flex020/uploads/builder/original/1X/9d36c17d504ac83df6f3a0a72e285b7516aac672.png) I’ve tried - Installing Chrome plugin - proxy previews - gatsby develop --https - Using the sample project versions of dependencies ie @builderio/gatsby 1.0.8 - Using the latest versions of all dependencies ie @builderio/gatsby 1.0.11 Making an edit does trigger a few events: - GET /api/v1/screenshot?.. HTTP 500 - GET /api/internal/get-max-box-sizes?.. HTTP 500 - Uncaught (in promise) SyntaxError: Unexpected token E in JSON at position 0 builderio looks so promising… can you help us get started? Thanks “Sorry, new users can only put 2 links in a post” - writing this post was a lot harder than it needed to be. ---

OK so it seems that the missing link is simply setting the ‘preview url’ to a page that doesn’t already exist such as **builder\_editing** as mentioned on [https://www.builder.io/c/docs/guides/preview-url](https://www.builder.io/c/docs/guides/preview-url). For a new user this github page [https://github.com/BuilderIO/gatsby-starter-builder](https://github.com/BuilderIO/gatsby-starter-builder) is the entire guide for using builderio with the gatsby framework but it doesn’t mention the preview url. Can I please suggest a review of the git readme and maybe a more detailed guide for gatsby users? I’d even suggest renaming ‘preview-url’ to something more like ‘building-url’… I thought it was supposed to be the url of the page I was viewing, especially as that’s what it defaults to! ---

There was an issue with editing and previewing due to a stale sdk version in the starter codebase, it’s all been resolved now after this PR was merged [https://github.com/BuilderIO/gatsby-starter-builder/pull/13](https://github.com/BuilderIO/gatsby-starter-builder/pull/13) Thanks for pointing this one out
