What is the issue when exporting a Spatially Enabled DataFrame to a Feature Class and encountering a KeyError?

edit

A KeyError while exporting a Spatially Enabled DataFrame to a Feature Class could indicate that the specified column(s) or field(s) do not exist in the DataFrame. This means that the export process cannot find the attribute information required for writing to the output Feature Class. It is important to ensure that the columns or fields used in the export are properly named and exist in the DataFrame before attempting to export it to a Feature Class.
