More detail on Value of type undefined not recognized exception

[danielovasSIO]

Is your feature request related to a problem? Please describe.
In case the object we want to write has an undefined value, the following exception is raised: Value of type undefined not recognized. It would make the problem identification much more easy if we could get the place/field the process found the problem.
Describe the solution you'd like
Two way iIcan imagine:

• in the error message it mention least the first element that triggered the exception.
• an additional field on the Error object like: effected_field ; that contains the name of the filed the exception triggered on.
