no output when querying --txs using a parquet file

[banteg]

Version
latest

Platform
linux

Description
I tried this code:

$ cryo transactions -i gas_used --txs ~/yearn/data/xen_txs.parquet

I expected to see this happen: output file written

Instead, this happened:

  "chunk_summary": {
    "n_completed": 0,
    "n_skipped": 0,
    "n_errored": 1,
    "paths": {
      "Transactions": [
        "/home/banteg/data/xen_transactions/ethereum__transactions__/home/banteg/yearn/data/xen_txs.parquet"
      ]
    }
  }
