Trello API Post broken

Hi people,

I can use the API project key and user token to view cards in trello. Up until recently, I could also post files onto those trello cards. Is the API partially broken at the moment or has something changed?

The error I now receive (in myJson.response) is: 

  <Response [404]>

I recreated my token and ensured it was marked for read and write permissions. From the 404 error, it appears to be a permissions issue, but the card being written to is newly created and using the same account tied to that token.

Any other ideas?





Here is my python function:

def addCardAttachment(trelloKey, trelloToken,filePath,cardId):

  import requests

  import json

  url = f"{cardId}/attachments"

  headers = {
    "Accept": "application/json"

  query = {
    'key' : trelloKey,
    'token' : trelloToken,

  files = {
    'file': open(filePath, 'rb'),

  response = requests.request(

  myJson = json.loads(response.text)
return myJson
