Theme not working after updating to Drupal 10.3.0

Hii @sis-sumados

This works fine for the Drupal 10.3.0 version. To install the base theme 'Classy' use the command: composer require drupal/classy:^1.0

I have tested it @Aman_Raj. The comment works fine here.

@sis-sumados, I have created a patch to resolve the Watchdog ERROR and substitute the error line as proposed.
This patch ensures that 'search-form__submit' is added to the class attribute array. If the class attribute is not already an array, this line will create an array and add the class to it.

Additionally, I am attaching a screenshot of the successful installation of the theme without any errors in the Drupal 10.3.0 version. Thanks.

Hi everyone. Thanks for your feedback an the patch. I have just correct a mistake. The correct line is:

 $form[$key]['submit']['#attributes']['class'][] = 'search-form__submit';

@sis-sumados, no worries. I've made the necessary updates to the correct line and created a corresponding patch. Please find the attached patch file for your review.
Moving this to RTBC. Thank you!
