In the examples for uniswapv2 real time, there is no function to decode pair created events. It just logs the event:

if log_result["event"].event_name == "PairCreated":
    logger.info(f"New pair created: {log_result}")
elif log_result["event"].event_name == "Swap":
    swap = decode_swap(web3, log_result)
    swap_fmt = format_swap(swap)
    logger.info("%s", swap_fmt)
else:
    raise NotImplementedError()

coming from https://web3-ethereum-defi.readthedocs.io/tutorials/live-swap.html

So I used the decode_pair_creatred function in the historical script exmple https://web3-ethereum-defi.readthedocs.io/tutorials/event-reader.html# but the job keeps crashing for different reasons when using that function in the live scenario.
Do you have an example or an extension of the live example with a working decode_pair_created function?
