QUESTIONS About REST HOOKs and issues on custom fields with NULL values

[jonaswebdev]

1. I was trying to process the requests from REST HOOKs using the method fill() to populate an AutopilotContact object but the "custom fields" standards are different.
   Do you have plans to support this in soon?

2. I'm experiencing issues with "custom fields" using values as null, throwing "typeMismatch" exception.
   I saw a possible solution on a forked repository.
   Also, this repository there is another improvement, it displays more details when an exception happens, It could be very helpful.
   Do you have plans to merge these improvements soon?
