thread 'blkfiles_fetcher' panicked

Hi, I've downloaded the Esplora, switched to new-index branch and run:
RUST_BACKTRACE=full cargo run --release --bin electrs -- -vvvv --db-dir /mnt/esplora-electrs-data/ --blocks-dir /mnt/data/bitcoin-core/blocks --utxos-limit 1000, but I am getting an error:

```
