* Hi,
* When editing any Page or Post while the website’s environment is set to ‘local’
or ‘development’, the following fatal error is displayed:
* `Function WP_Styles::add was called incorrectly. The style with
the handle "sbi_styles" was enqueued with dependencies that are not registered:
sbi-tokens-local. Please see Debugging in WordPress for more information.(
This message was added in version 6.9.1.)`
* Switching to production or staging environment mode causes the problem to go
away, but of course we need to work on the website in a local / development environment.
* If you need any further info please let me know.

* Hi [@factory44](https://wordpress.org/support/users/factory44/),
* Thank you for reporting this, and for the detail you included.
* I’ve shared this with our development team and so they can address it in an upcoming
release.
* In the meantime,jthe code below should clear it. You can add this using a free
plugin like [WPCode](https://wordpress.org/plugins/insert-headers-and-footers/),
add it as a PHP snippet with the location set to Run Everywhere.
* ```wp-block-code
add_action( 'enqueue_block_assets', function () {
if ( ! defined( 'SBI_PLUGIN_URL' ) || wp_style_is( 'sbi-tokens-local', 'registered' ) ) {
return;
}
wp_register_style( 'sbi-tokens-local', SBI_PLUGIN_URL . 'assets/tokens/sb-tokens-local.css', array(), SBIVER );
}, 0 );
```
* If you need any assistance setting that up or if you have any other questions,
please let us know.
* Thanks!
