Erase custom field

[Roman Solo]

I have custom field for my project in jira v7. I can't figure how to erase value from that field. I'm tried this api request with parameter: 

{ "fields": {"customfield_10201": ""}}

 But it seems to ignore empty value in the request. In my program I modify others values (not empty) and it works fine.

Got it. You need to pass null value to empty custom field.
