existing_invoice_not_cancellable
Existing invoice not cancellable. HTTP status 409.
Changing the billing cycle needs the pending renewal invoice to be cancelled and replaced. That invoice cannot be replaced automatically, for example because it also bills other services.
What to do
Pay the invoice in existingInvoice with POST /api/v2/billing/invoices/{id}/actions/pay. Then send the billing cycle change again.
