Button - simultaneous use "Gradient Fill" and "Outline" - causes "Error 500" when trying to save the page

[oldgamer1974]

Button - simultaneous use these options - causes "Your server returned a 500 error." when trying to save the page:

• using a "Gradient Fill" ("Linear" or "Radial") as the background of the button, instead of "Solid"
• using an "Outline=ON" for the button

If under "Your server returned a 500 error." I click on "SEE DETAILS" > "ERROR DETAILS" - more detailed information about the errors is displayed:

Breakdance\AJAX\BreakdanceAjaxHandlerException: An exception has been thrown during the rendering of a template ("Array to string conversion") in "177273b38164851f6acbf973d4cdc417e031ac40" at line 13. in C:\xampp\htdocs\shop-test.com\wp-content\plugins\breakdance\plugin\ajax\api.php on 116

throw new BreakdanceAjaxHandlerException($callback_exec_exception->getMessage(), 500, $callback_exec_exception);

This issue was already posted by another user here (Jul 8, 2024):

But there in response other users could not confirm this issue, because the author did not specify that the issue occurs only under simultaneous using "Gradient Fill" and "Outline=ON" - he only specified that "customize it with a background gradient".

My Software and Settings:

Platform: PC Windows 10 x64
WEB-Browser: CHROME 131.0.6778.86
Server: Localserver XAMPP 8.2.12
PHP: 8.2.12
Apache 2.4.58
MariaDB 10.4.32

I have the following software versions installed:

• Wordpress 6.7.1
• WooCommerce 9.4.2
• Breakdance Pro 2.2.0-rc.1

> I have "Debug Mode" enabled in "WordPress"
(this helps me quickly detect critical glitches in the plugins)
I have these lines in the "wp-config.php" file :
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
define( 'SCRIPT_DEBUG', false );

P.S.
I hope this problem will be fixed soon, because it is critical for the design of my website, for which I purchased the "Breakdance Pro" license, and I am pressed for time before the planned launch of the website.

Today I updated Breakdance to version 2.2.0 (instead of 2.2.0-rc.1) - nothing changed, the problem remains...
