file is not a database

[iamyb]

Hello, thanks for the wheel first.

I met one error when add "PRAGMA journal_mode" into my code. any idea about it?

sqlalchemy.exc.DatabaseError: (sqlcipher3.dbapi2.DatabaseError) file is not a database_

@event.listens_for(Engine, "connect")
def set_sqlite_pragma(dbapi_connection, connection_record):
    if isinstance(dbapi_connection, SQLite3Connection):
        cursor = dbapi_connection.cursor()
        cursor.execute("PRAGMA journal_mode;")
        # cursor.execute('PRAGMA wal_checkpoint=TRUNCATE;')
        cursor.execute("PRAGMA foreign_keys=ON")
        cursor.close()

• Is the file really a database? You can check by trying to open the file with programs like DB Browser
• Correct key?
• Correct sqlcipher version?
• Does the problem only occur when executing "PRAGMA journal_mode"?
