Custom Date Field via API

We are trying to update a custom date field: https://az-am-ent-f14.corrigo.com//api/v1/base/CustomField2

Here is the payload:

{'Entity': {'Descriptor': {'Id': 48}, 'ObjectTypeId': 'WO', 'ObjectId': 3018001, 'Value': '2025-09-29T00:00:00'}}

Here is the response: {'ErrorMessage': "Provided value isn't compliant with data type Date.", 'ErrorCode': 'ERROR_CODE_1', 'TimeStamp': '2025-09-30T16:34:21.3956281Z'}

Can you please advise on best way to proceed?
