Error in drying to drop column that doesn't exist.

HeatCluster is throwing an error:

/workspace/heatcluster/heatcluster.py:55: PerformanceWarning: Determining the column names of a LazyFrame requires resolving its schema, which is a potentially expensive operation. Use `LazyFrame.collect_schema().names()` to get the column names without this warning.

Where would I insert 'LazyFrame.collect_schema().names()' as suggested in the error above? And would I remove 'df = df.drop("0")'?
