Bulk GraphQL Export Errors

[satish_repeat]

Hello,

We've been attempting to export orders for a store using the bulk GraphQL API. After running for ~20 hours we received an "INTERNAL_SERVER_ERROR" after polling for the status of the operation. We've tried similar queries of varying size (by filtering "created_at") with mixed results. We occasionally receive a "COMPLETED" result but not consistently. We'd like a reliable way to export order data.
