Fatal error caused by “BpostNotImplementedException” when printing label

Dear Support,

When I tried to print the label for an international shipping method, I obtained a fatal error. The log from bpost-shipping regarding this error is:

2021-03-25T09:09:09+00:00 CRITICAL Uncaught Bpost\BpostApiClient\Exception\BpostNotImplementedException: Not implemented: No createFromXML found into \Bpost\BpostApiClient\Bpost\Order\Box\Option\Insured in /var/www/delforge/wp-content/plugins/bpost-shipping/vendor/antidot-be/bpost-api-library/src/Bpost/Order/Box/International.php:241

Do you have any ideas on what could cause this error?

Best regards.
