The property phone_number is required while registering the shipment.
This error is occurring when recipient’s phone_number parameter is not sent in the Shipment API https://api.myparcel.com/shipments
According to the Spring Omni documentation, phone_number is an optional parameter:
We raised ticket on Spring Omni and they replied: The shipment is failing to be created due to recipient phone number not being populated. Although, the schema shows this as optional but Spring require the phone number so the carriers can send notifications to the recipient (if they offer that service…)
So phone_number is a required parameter and need to be sent in shipment API.
