crates/apollo_l1_provider/src/l1_provider.rs line 248 at r1 (raw file):

                            "Double consumption of {tx_hash} at {consumed_at}, previously \
                             consumed at {previously_consumed_at}."
                        );

Why is this a panic?

Code quote:

                        panic!(
                            "Double consumption of {tx_hash} at {consumed_at}, previously \
