[Python] Getting data inside a google Chrome IndexedDB from Bash or Python

I have LevelDB (IndexedDB) file from my Google Chrome, the file is located in this folder:

/home/<user>/.config/google-chrome/Default/IndexedDB/https_<site>_0.indexeddb.leveldb/


The folder content is:

$ ls
000005.ldb 000006.log CURRENT LOCK LOG MANIFEST-000001

#!/bin/python
import leveldb
db = leveldb.LevelDB('./000005.ldb')

leveldb.LevelDBError: IO error: ./000005.ldb/LOCK: Not a directory
