In structlog, the event data should be passed as key-value pairs inside a dictionary so that the processors can modify the log event as needed.
Here's how you can fix this issue based on your provided log:
Incorrect Usage
You might be logging like this:
Copy
Correct Usage
You should structure your log message as a dictionary:

Here's a more detailed explanation and correct implementation:
Correcting the Logging Call
When using structlog, it's important to pass structured data as keyword arguments, not as formatted strings. Here's how you can update your logging statement:
Copy
In this corrected version:
'Operation completed' is a simple description of the event.
result=result ensures that result is logged as a key-value pair in the structured log. This format allows structlog's processors to correctly manipulate and render the log data.
Structlog Configuration
Make sure your structlog is properly configured to handle structured logs. Here's a basic setup example:

Using the Logger
With the correct setup, you can now log structured data, which is particularly useful for complex data types and when logs are ingested into log management systems that support querying and indexing structured data.
Copy
This structured approach ensures that each part of the data can be individually accessed and processed by the logging system or by any log management tool you might be using, enhancing the capability to filter and analyze logs.
