Summary:

How to Assign a value of Null to a Date field in a REST inbound transmission?

Content (required):

Assigning null to a GID column works. "planToLocationGid":""

However how to do the same for a Date Field?

Tried the following but it returns a HTTP 400 Bad Request.

 "lateDeliveryDate": "~"

 "lateDeliveryDate": { "value": "~" }

 "lateDeliveryDate": { "value": "" }

The last one does not error out at the time of handshake however it does not update it to null either :(

 "lateDeliveryDate": null,
