confluent_kafka.Message.headers() returns incorrect value

[rudo-ro]

Initial Checks

• I confirm that I'm using Types-Confluent-Kafka

Description

https://docs.confluent.io/platform/current/clients/confluent-kafka-python/html/index.html#confluent_kafka.Message.headers

in the docs I'm seeing

headers()

    Retrieve the headers set on a message. Each header is a key valuepair. Please note that header keys are ordered and can repeat.

    Returns

        list of two-tuples, one (key, value) pair for each header.
    Return type

        [(str, bytes),…] or None.

In the code I'm seeing;

    def headers(self) -> list[tuple[str, str | bytes]] | None: ...
