  Check the OData Service Metadata: Review the metadata of the OData service to confirm which properties are defined as non-nullable. This can usually be accessed via the service's $metadata endpoint.
  Review the Request Payload: Ensure that the request being sent to the OData service includes a valid value for the property that is causing the error. If the property is required, it should not be omitted or set to null.
  Update the Application Logic: If the application logic is responsible for constructing the request, ensure that it correctly populates all required fields before sending the request.
  Testing: After making the necessary changes, test the request again to ensure that the error is resolved.
