Multipart Reader failure - 'content-type' was not found

Hello all,

I'm successfully using Postman to submit a file and payload to a SnapLogic triggered task using the Multipart Reader snap, however when I try the same using Python, I'm getting an error like this one:

{
"failure" : "Pipeline execution failed while waiting for output",
"reason" : "Snap errors: {ruuid=653b762b58a6244b73fecf7a_1388887b-924e-4356-b1e6-b05868cf03bf, reason='content-type' was not found while evaluating the sub-expression '$['content-type']', label=Binary Router, resolution=Check the spelling of the property or, if the property is optional, use the get() method (e.g. $.get('content-type')), failure=$['content-type'] is undefined. Perhaps you meant: 'Content-Type', 'Content-Length', 'Connection', 'CONTENT_TYPE'}",
"resolution" : "Fix the reported errors"
}

The Python sample was generated by Postman and didn't include any 'Content-Type' defined:

import requests

url = "https://MyURL.com?bearer_token=abc123"

payload = {'fileName': 'fileName.jpg'}
files=[
  ('file',('file.png',open('file.png','rb'),'image/png'))
]
headers = {}

response = requests.request("POST", url, headers=headers, data=payload, files=files)

print(response.text)

I added the 'content-type' in the headers like below, but it doesn't change anything, I'm getting the same error.

import requests

url = "https://MyURL?bearer_token=abc123"

payload = {'fileName': 'fileName.jpg'}
files=[
  ('file',('file.png',open('file.png','rb'),'image/png'))
]
headers = {
    'Content-Type' : 'image/png'
}

response = requests.request("POST", url, headers=headers, data=payload, files=files)

print(response.text)

I'm using the Multipart Reader snap the default values.

Does anyone know how to resolve this issue?

Thanks in advance for any help!

Kind regards,

JF
