exports.blockers

List what is holding exports back, grouped into the questions a person answers once for many documents: which account paid (payment_account), receipts with no payment details (receipt_draft), supplier invoices with no matching QuickBooks bill (quickbooks_unpaid_bill), which QuickBooks company to use (accounting_destination), and which business a supplier's documents belong to (entity_assignment). Each blocker names the export(s) to answer through. A connection that is disconnected or removed cannot send anything until it is reconnected. Read only; answer with exports.resolve.
