# JavaScript error on “Site Editor (Beta)” page

 * Out of pure curiosity I enabled the “Site Editor(Beta)” on a local test site.
   There’s a JavaScript error on its page:
    `Uncaught (in promise) SyntaxError: 
   JSON.parse: unexpected character at line 1 column 1 of the JSON data` that point
   to this file: /wp-content/plugins/gutenberg/build/redux-routine/index.js
 * Looking at the network tab I found a request initiated by this index.js file,
   and it’s URL is:
    `mysite.com/?_wp-find-template=true` However, the WordPress
   installation I’m working on is located at `mysite.com/wp_test/`. In the browser’s
   URL bar I see this address: mysite.com/wp_test/wp-admin/admin.php?page=gutenberg-
   edit-site So I think somehow the wrong URL is fetched.
 * I have no WordPress installation on `mysite.com`. That’s a simple HTML page, 
   which starts like this:
 *     ```
       <!DOCTYPE html>
       <html>
       <head>
       	<title>Testing sites</title>
       ```
   
 * I’m running WordPress 5.5.1 and Gutenberg plugin is 9.0.0. No other plugins enabled.
   Theme is TwentyTwenty.
