Please enable SDK logs via https://github.com/awslabs/aws-crt-python/blob/main/awscrt/io.py#L28 and attach Trace level logs for a run of the sample.

[bretambrose]

Scratch that, the sample is obviously wrong: https://github.com/awslabs/aws-crt-python/blob/main/awscrt/mqtt.py#L816-L818

The print statement should be updated to not read anything from the future's value (as packet id is useless) and just indicate that the publish was successful.
