AJAX error when editing shipping address

I can sadly confirm this with latest 8.x-2.40 on latest Drupal 10.

Some more details from the logs:

Maybe an AJAX callback has a missing "static"?
See https://julian.pustkuchen.com/en/external-drupal-ajax-callback-methods-m...

Hope I'll find some time for further investigations.

Seems to happen in regular customer checkout.

Shouldn't that be a commerce_shipping issue? I don't see commerce in the stracktrace though...

Thanks @jsacksick sorry I didn't see that! Moved over to Commerce Shipping!

Seeing similar issue.

After trying to edit the address the following error message appears:
Oops, something went wrong. Check your browser's developer console for more details.

Checking to developer console shows the following error message

Drupal.AjaxError
message
:
"\nAn AJAX HTTP error occurred.\nHTTP Result Code: 500\nDebugging information follows.\nPath: /checkout/5226/order_information?ajax_form=1\nStatusText: error\nResponseText: The website encountered an unexpected error. Try again later."
name
:
"AjaxError"

Looking to the dblog shows the following error:

Warning: Trying to access array offset on null in Drupal\commerce_shipping\Plugin\Commerce\Condition\ShipmentWeight->evaluate() (line 138 of mysite/modules/contrib/commerce_shipping/src/Plugin/Commerce/Condition/ShipmentWeight.php)
