What was wrong?

Copy/pasted from gitter:

Hi all, I'm not sure if this is the right place to ask, but I've been getting the same error as @rodrigosobrero, attempting to do something presumably similar.

I have a private PoA network setup with geth nodes, and I have a portion of a smart contract that emits an event like so:

emit Sent(test_package);

The event is defined as:

event Sent(Test[] test_package);

where Test is a struct defined as follows:

struct Test {
    int[12] features;
    address owner;
}

I am using the following code to listen for the event, and just try to print it out:

block_filter = smart_contract.events.Sent.createFilter(fromBlock=0, toBlock='latest')

while True:
    for event in block_filter.get_new_entries():
        print(event)
    time.sleep(2)

But whenever a new event comes in I get the same stacktrace eth_abi.exceptions.NoEntriesFound: No matching entries for 'tuple' in decoder registry. I've attached a full traceback here if it's useful.

Web3.py version 5.7.0
eth-abi version 2.1.1

Any guidance is appreciated. Thanks!
