I am trying to send POST request to following API: https://2captcha.com/2captcha-api (look at normal captcha).



Here is my code



library(httr)



captcha_apth <- paste0("my_image_path.jpeg")



output <- httr::POST(

  url = api_url,

  body = list(key = api_key, method = "post", file = httr::upload_file(captcha_apth)),

  encoding = "multipart",

)


but it returns an error:



ERROR_ZERO_CAPTCHA_FILESIZE


It seems like it doesn't upload the image, but I can't figure out why?






r post httr
