Error on receiving shipment_status_change webhook

[EdieLemoine]

Module version

1.7.0

PrestaShop version

1.7.8.7

PHP version

7.3.27

What went wrong?

When an order label does not exist, like when it has been deleted, when receiving a shipment_status_change webhook, an error occurs and triggers a 500 Internal Server Error.

Also occurred with module version 1.6.3

Reproduction steps

1. Have webhooks and automatic order status based on shipment status set up
2. Receive shipment_status_change webhook

FYI: This happened when the label doesn't exist, presumably was deleted.
