Ich wei?, es ist kein Error, sondern nur eine Notice, sollte aber dennoch behoben werden…

Alles neueste Versionen.

Das ist diese Zeile hier:

if ( ! empty( $chosen_shipping_methods ) ) {
		$method = wc_gzd_dhl_get_shipping_method( $chosen_shipping_methods[0] );

		return $method;
	}

Ich habe hier mal ein print_f eingefügt und das Array sieht an der Stelle so aus:

$chosen_shipping_methods: 
Array ( [2022_01_01_monthly_synced_0] => free_shipping:2 ) 

Es ist also eher ein Dictionary bzw. eine Map statt eines 0-indexed Arrays.
