Form####Serializer::deserializeCollection Method Error: "The type of object cannot be set."

Applies to Product - Dynamics 365 Finance
 

What’s happening?
The customer is experiencing an error with the Form####Serializer::deserializeCollection method, specifically receiving the message "The type of object cannot be set."
 

Reason:
This is related to a known problem or design limitation that is outside the supported scope of technical assistance.
 

Resolution:

1. Investigate if the error occurs when attempting to delete a vendor bank account from the VendBankAccounts form. The error may arise if there are dependencies on the vendor that prevent deletion.
2. Ensure that before deleting a VendBankAccount record, the corresponding account field on the VendTable Payment tab is cleared.
3. If multiple vendor bank accounts are set up, verify that the system is not still referencing the original bank account. Expiring other bank account records may force the system to use the new bank account.
4. Confirm with the customer that the issue is beyond the technical support scope and provide any relevant documentation as a reference.
