As we can see there is an error in your package related to the mapping ‘The property value '1ab406172c' has not a valid format.’ error means that an Id field was mapped to a ‘1ab406172c’ constant instead of a Target/Source Lookup Mapping.
Please try to configure a mapping to be like that in the package:
As for custom fields update, have you tried to implement it in your package? Were there any difficulties?
Please let us know if any.
We look forward to hearing from you.
