ValueError: The length of the provided data is not a multiple of the block length.

[savathuntechquestion]

I've been getting this error midway through trying to download a series. My input is kisskh dl "https://kisskh.co/Drama/Mysterious-Lotus-Casebook?id=7648" -f 9 --decrypt-subtitle --key "8056483646328763" --initialization-vector "6852612370185273"

I'm starting at episode 9 because ep 9 is what it fails at

Where I'm using the vektor and decryption key from this post since I'm not sure how to generate my own key or vector.

Full text of the error:
