Error running "python3 -m telegram_export"

[njscorpion]

Hi,

I installed clone version of git, using Linux Mint 19 Tara, Kernel: Linux 4.15.0-54-generic. on running python3 -m telegram_export i am presented with the following error :

Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/usr/lib/python3.6/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/home/**removed**/.local/lib/python3.6/site-packages/telegram_export/__main__.py", line 316, in <module>
    ret = loop.run_until_complete(main(loop)) or 0

    return future.result()

    exporter = Exporter(client, config, dumper, loop)
  File "/home/**removed**/.local/lib/python3.6/site-packages/telegram_export/exporter.py", line 54, in __init__
    self.downloader = Downloader(client, config['Dumper'], dumper, loop)
  File "/home/**removed**/.local/lib/python3.6/site-packages/telegram_export/downloader.py", line 52, in __init__
    assert all(x in VALID_TYPES for x in self.types)
AssertionError

The following is my config :

[TelegramAPI]
ApiId = 123456
ApiHash = 00000000000000000000000000000000
PhoneNumber = +000000000000
SessionName = exporter
[Dumper]
OutputDirectory = /home/**removed**/Downloads/*****_10am
Whitelist = -1234567891234 
MediaWhitelist = "photo", "document", "video", "audio", "sticker", "voice", "chatphoto"
MaxSize = 3000MB
LogLevel = INFO
DBFileName = export
MediaFilenameFmt = usermedia/{name}-{context_id}/{type}-{filename}
InvalidationTime = 7200
LibraryLogLevel = WARNING

By the way "python3 -m telegram_export --list-dialogs" works fine. Please assist!
