Panic - Index out of range

I was running a script to populate a minio bucket locally using the following script:

#!/bin/bash

db_file='db.sqlite'
bucket='local/reflector'

export bucket

copy_to_s3() {
  blob_hash=$1
  mc cp blob "${bucket}/${blob_hash}"
}

export -f copy_to_s3

sqlite3 -list -noheader "$db_file" "SELECT blob_hash FROM blobs" | xargs -I {} -P 16 bash -c 'copy_to_s3 "$@"' _ {}

the database contains 80k entries with random strings (hashes). for each single hash (you can just randomly generate them) it copies a small text file to the S3 bucket locally using the mc client

I suppose that the script causes some sort of race condition while printing to the terminal (using colors).

see this screenshot for when it happened: https://scrn.storni.info/2023-07-26_00-59-21-324108027.png

I'm on Kubuntu 22.04 using konsole 21.12.3 if that helps.
