Error trying to update contact to be active instead of trial

[QualityAssurance2]

I try to update the the account to be active and keep getting :

Array ( [response] => [{"error_key":"email","error_message":"billing.customer.email.required"}]

      [http_code] => 400 ) 

The account in trial mode I use put method to send this array to make the account active

{

"plan_type": 2,

"billing_day_of_month": 20

}

but still getting the error above
