Help with Base64 - python - polars column Names

Hey guys I am trying to figure out if I am doing this right. I have figured out to how to read and decode a csv file in python, but when I return a polars dataframe it is missing columns names and just giving me numbers. Am I missing something?

Test-Code

import base64
import polars as pl

def main(base_str):
    base64_string = base_str
    sample_string_bytes = base64.b64decode(base64_string) 
    #return sample_string_bytes.decode()
    return pl.read_csv(sample_string_bytes)

import base64
import polars as pl

def main(base_str):
    base64_string = base_str
    sample_string_bytes = base64.b64decode(base64_string) 
    #return sample_string_bytes.decode()
    return pl.read_csv(sample_string_bytes)

Hi @Mearthy, I think you're missing a toDicts to have an array of objects:

import polars as pl

def main(base_str: bytes = bytes(0)):
    csv = pl.read_csv(base_str)
    return csv.to_dicts()

import polars as pl

def main(base_str: bytes = bytes(0)):
    csv = pl.read_csv(base_str)
    return csv.to_dicts()
