Critical error when using JavaScript Redirect masking option

Hello,

I’m experiencing a critical error with the No External Links plugin and would like to report a possible bug.Critical error when using JavaScript Redirect masking option

Steps to reproduce:

1. Go to No External Links settings.
2. In Masking Type, select JavaScript Redirect.
3. Enter any content into the JavaScript Redirect Text field.
4. Click Save.

Error message:
Uncaught Error:
Mihdan\No_External_Links\Admin\Admin::sanitize_text_array_deep():
Argument #1 ($arr) must be of type array, null given,
called in /s2-decideletters/wordpress/wp-includes/class-wp-hook.php on line 343
in /s2-decideletters/wordpress/wp-content/plugins/mihdan-no-external-links/admin/Admin.php on line 2361

Call stack:

• Mihdan\No_External_Links\Admin\Admin::sanitize_text_array_deep()
• wp-includes/class-wp-hook.php:343
• WP_Hook::apply_filters()
• wp-includes/plugin.php:205
• apply_filters()
• wp-includes/formatting.php:5135
• sanitize_option()
• wp-includes/option.php:887
• update_option()
• wp-admin/options.php:345

It looks like sanitize_text_array_deep() is receiving null instead of an array when saving this option.

I would really appreciate it if you could take a look or let me know if there’s a workaround or fix planned.

Thank you very much for your support.
