Hi @serdarjan1995 

Can’t you map the output python file to Dropbox upload file action?

Nope, if I remove Python Code from zap and connect direcly Trigger with the Dropbox upload file action the file is uploaded to properly.

Here is snipped of Python code
 

import csv
import io

# attachment is the file from Dropbox
file_buff = io.StringIO(input_data.get('attachment'))
csv_data = csv.DictReader(file_buff)
csv_lines =  ]
for l in csv_data:
    ### parse data here in loop
    csv_lines.append(l)

parsed_csv = io.StringIO()
csv_writer = csv.DictWriter(parsed_csv, csv_data.fieldnames)
csv_writer.writeheader()
csv_writer.writerows(csv_lines)

# move file ptr into beginning and read as string
parsed_csv.seek(0)
data = parsed_csv.read()

# data - is a string
output = {'parsed_csv': data, 'fieldnames': csv_data.fieldnames}
parsed_csv.close()

I have mapped `parsed_csv` to the Dropbox. When Zap runs outcome in Dropbox file is not csv, rather it contains string : `hydrate|| ………..`
