I am trying to expand Odata for a lookup field with the expand query, but it is not working and throwing error message:

"Could not find a property named 'crd18_vp_truckid' on type 'Microsoft.Dynamics.CRM.crd18_vp_inventorymaster'."

Here "CRM.crd18_vp_inventorymaster" is the logical name of the custom entity and "crd18_vp_truckid" is the custom type lookup field.

Below is the GET request I am processing:
https://org6acdaf1a.crm.dynamics.com/api/data/v9.0/crd18_vp_inventorymasters?$expand=crd18_vp_truckid

Getting the below reposne(error):

Please suggest me solution for the same or I am doing something wrong.
