Today, I was attempting to use the 'Expand' feature in the web api to help me with a lookup field on my custom dataverse table. No matter what I did, I could get it to work. It kept telling me that my property 'ver_dataareaid' didn't exist on my table. It, obviously, did so I knew I was doing something wrong. When using the 'Expand' you need to use the Schema name of the field:
As you can see, the 'Schema name' can be found under the 'Advanced options' when you 'Edit' the column. This gave me the actual 'Name' value of the column rather than a guid from the lookup.
