KeyError: 2 when converting

[LotfiKobrosly]

Hi! I am using the nano-tools in this repository on the test network I created on my computer using docker-compose, and I have two errors (which I cannot understand):

1. Creating the dump for the database:
   When I run python3 dump_wallet_db.py , it tries to accede to the dump but it stops after a second with this response:

Traceback (most recent call last):
  File "dump_wallet_db.py", line 225, in <module>
    subdb = env.open_db(subdbname.encode())
lmdb.ReadonlyError: mdb_dbi_open: Permission denied

2. When running ./conv2sqlite.py convert after exporting LC_ALL=C.UTF-8 and LANG=C.UTF-8 I get:

Reading the Nano database at /root/RaiBlocksTest/data.ldb

    assert block_to_type[send_block] == 'send'
KeyError: 2

Can anyone help me understand and fix this please? Thank's a lot!

For the second issue I suspect that the new universal blocks are somehow to blame, as I haven't added support for them.

For the first issue I can't directly see what is happening. What is the size of the RaiBlocks folder you're working with?
