ValueError: Unable to configure handler 'file_handler'

[okoliechykwuka]

I get the below error when I run streamlit run layout_clean_sidebar.py -- prd. The error is coming from line 18 in metrics.py

logging.config.dictConfig(config)

How can I fix this

Open the file being called by metrics.py (by the get_perf_logger() function) called "perf_logging.yaml". In this file, the path to perf_metrics.log in the handler's "filename" parameter is incorrect.

Create a new perf_metrics.log somewhere in the streamweb folder, get its path on your system, and paste the path into the filename parameter on the "perf_logging.yaml" file.
