Random error while decrypting database

[xxxwww]

Regular class initialization

client = Telegram(
    api_id=self.api_id,
    api_hash=self.api_hash,
    library_path=self.library_path,
    phone='+XXXXXXXXXXXX'',
    database_encryption_key='XXXXXXXXXXX',
    use_test_dc=True,
    files_directory=self.files_directory,
    use_message_database=False,
    login=True,
)

Randomly causes an error

Telegram error: {'@type': 'error', 'code': 401, 'message': 'Database encryption key is needed: call checkDatabaseEncryptionKey first', '@extra': {'request_id': 'updateAuthorizationState'}}

Next time you start everything can work fine

[tomtao007]

hello, can you resolve this issues? how to ?

[peterus]

With last Version 0.8.0 the issues are not so often anymore, but still be seen.

[alexander-akhmetov]

As I see in the logs, the library sent setTdlibParameters twice. Probably, this is why the problem happens. I will try to release a fix soon.

[alexander-akhmetov]

Should be fixed in version 0.9.0. Please, reopen the issue if you will have the same problem.
