Description

opened on Feb 20, 2026

Apache Airflow version

3.1.7

If "Other Airflow 3 version" selected, which one?

No response

What happened?

structlog error was raised when a dict is passed as an argument to a logging message.

What you think should happen instead?

It should be able to print the string representation of the dict passed as an argument

How to reproduce

Run this file. You can see that it succeeds and behaves as expected if you remove the import airflow

import logging
import airflow

logging.getLogger(__name__).warning('Info message %s', {'a': 10})

Operating System

Debian GNU/Linux 12 (bookworm)

Versions of Apache Airflow Providers

No response

    One more detail in case it's relevant: this only fails when the dict has a length of 1. It works for dicts of other sizes.
