TypeError: validateThemeColors is not a function

[sdoigmm]

I am unsure if we can use LocalWP sites using a URL different to localhost, and if not, that might be the cause of this problem.

Describe the bug

Following the backend process, all plugins except

• DS Headless (Gravity Forms)
• WPGraphQL for Gravity Forms

are active

When creating a new page using Gutenberg, there is an error when adding any block:
This block has encountered an error and cannot be previewed.
and a console error
TypeError: validateThemeColors is not a function.

Activating the wds-headless-theme does not resolve this.

To Reproduce

1. Follow the steps for the backend:
2. Create a new WP site using LocalWP on macOS
3. Install Composer
4. Install & activate Plugins and Theme
5. Configure wp-config.php
6. Create a new Page where the error will occur

Expected behavior
You should receive no error when adding a new block to a new page.

Screenshots

Desktop (please complete the following information):

• macOS Ventura 13.3.1
• Chrome Version 113.0.5672.126
• LocalWP 6.7.1, PHP 7.4.30, WP 6.2.2.
• wds-headless-theme Version 1.0.0

Additional Notes

• After activating wds-headless-theme, the gutenberg editor layout looked a bit broken:
  
• There is also a console error on the page editor screen: Failed to load resource: net::ERR_CONNECTION_REFUSED: http://localhost:3000/?page_id=18&_wp-find-template=true&_locale=user
• Deactivating wds-headless-theme and activating Twenty Twenty Three makes the editor layout look unbroken:
