Different nodes report different hashes, and none of them reference valid tx's.

Observed on testnet. When there is no op in a block, the vop gets an invalid trx_id, which explains why it would be rarely observed on mainnet.

curl -s --data '{"jsonrpc":"2.0","id":"1","method":"condenser_api.get_ops_in_block","params":[417041,false]}' https://testnet.steemitdev.com
