When trying to import Name and email to zendesk
I get error : "The value of the column DomainNames has incorrect JSON format"
I can see in the errors csv that the values are correct.
Zendesk DomainNames field (Organization table) stores values in the JSON format, for example:
Thus, simple column mapping will not work. You should either have field storing values in such format in your database or use Constant mapping (if this suits your scenario).
