When an order comment is added via the Magento API by MintSoft, the 'entity_name' field is not populated with the value 'order'.
This causes null values to be stored in the Magento database.
Idea to resolve Problem
Add the 'entity_name' field with value 'order' to order comment API calls. The API does say this is optional and it looks like a shortcoming of the Magento API but it could easily be included. https://adobe-commerce.redoc.ly/2.4.6-admin/tag/ordersidcomments#operation/PostV1OrdersIdComments
