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?
