BUG | When using Aerospike with tumbling windows, the config is not loaded

[pedro-a-n-moreira]

So, I'm using the latest version of Faust with an Aerospike database for persistence. I have followed the instructions in the project's README.md, but I still get this issue with tumbling windows:

Here is my code:

sum_transactions_table = (
    app.Table(
        'transactions-sum',
        default=float,
        partitions=config.faust.partitions,
        on_window_close=window_processor,
        options={'namespace': 'default', 'client': {'hosts': [('127.0.0.1', 3000)]}},
    )
    .tumbling(
        config.faust.window_closing_time,
        expires=timedelta(hours=config.faust.window_expires),
        key_index=True
    )
)

This produces the following error output:

[2025-01-30 12:42:00,764] [10813] [ERROR] Error configuring aerospike client 'NoneType' object has no attribute 'get'

Note that removing the .tumbling() method makes it work. So looks like it is not loading the config from the table.
