HI, I'm trying to parse a csv file which was exported from spreadsheet, but the csv parser failed when a cell doesn't have any value:
import "package://pkg.pkl-lang.org/pkl-pantry/pkl.csv@1.0.0#/csv.pkl"
data = """
Column1, Column2, Column3, Column 4
Value 1, Value 2,, Value 4
"""
csvData = new csv.Parser {
input = data
includeHeader = true
}.parsed
But got pkl error:
–– Pkl Error ––
Expected value of type `String`, but got `null`.
188 | let (header: List<String>? = (if (includeHeader) stringyResult[0] else properties?.keys)?.toList() as List<String>?)

Coming from python's csv (I know it's apple to orange comparison, but anyway), I don't expect this error.
