Cannot read any leveldb (IndexedDB) from Skype for Desktop #119
Description
Hi!
I tried to use this lib without success to read two leveldb produced by Skype app:
SKYPE_DATA_DIR/IndexedDB/file__0.indexeddb.leveldb
and
SKYPE_DATA_DIR/Local Storage/leveldb.
For the first I needed to register a custom comparator: idb_cmp1
options.comparator(new DBComparator() {
@Override
public String name() {
return "idb_cmp1";
}
@Override
public byte[] findShortestSeparator(byte[] start, byte[] limit) {
return start;
}
@Override
public byte[] findShortSuccessor(byte[] key) {
return key;
}
@Override
public int compare(byte[] o1, byte[] o2) {
return new String(o1).compareTo(new String(o2));
}
});But for both I received this error:
Exception in thread "main" java.lang.NullPointerException

I already tried to disable compression on Options.
Did anyone read Skype App database with this lib? (aka Electron/Chromium IndexedDB)
