Hi! I have problem when I try upload an image using Cloudinary, I don't know what happen. This is my code:

def add_media(update, context):
  send_photo = upload('http://res.cloudinary.com/demo/image/upload/couple.jpg')
Enter fullscreen mode Exit fullscreen mode

The console show:

2021-07-15 14:01:44,494 - telegram.ext.dispatcher - ERROR - No error handlers are registered, logging exception.
Traceback (most recent call last):

    filename, data = value

Enter fullscreen mode Exit fullscreen mode

Does anyone have any idea what is going on?

Hi, this doesn't seem like the code i wrote in the demo, for this article, however this doesn't look like the code to upload an image to cloudinary looks like. You might want to check the docs or use the one i wrote on the product_info method in handlers.py from the tutorial.

I get the same problem when doing the demo, that's why I simplified it.

def add_media(update: Update, context: CallbackContext):
  logger.info(f"El usuario {update.effective_user['username']}, subió foto")
  quote = context.user_data["new_quote"]
  photo = context.bot.getFile(update.message.photo[-1].file_id)
  file_ = open("product_image", "wb")
  photo.download(out=file_)
  send_photo = upload("product_image", width=200, height=150, crop='thumb')
Enter fullscreen mode Exit fullscreen mode 
dp.add_handler(ConversationHandler(
  entry_points = [CommandHandler("new", handlers.start)],
  states={
    handlers.QUOTE: [
      MessageHandler(
          Filters.all, handlers.add_quote
      )
    ],
    handlers.MEDIA: [
      MessageHandler(Filters.photo, handlers.add_media)
    ]
  },
  fallbacks=[CommandHandler('cancel', handlers.cancel)],
  allow_reentry=True)
)
Enter fullscreen mode Exit fullscreen mode

The console show the same error:

ValueError: not enough values to unpack (expected 2, got 1)
Enter fullscreen mode Exit fullscreen mode

I know the error is upload because when I remove it the error does not appear.

I see, do you add caption to the image when you test it though.?

Could you check my code and see if there is something I am doing wrong?

github.com/alvaaz/telegram_bot

I would really appreciate it
