curl exited with exit code 22

Everytime I run pantran in any way I get a vim.notify notification with the contents "curl" exited with error code 22!.

latest pantran version neovim version NVIM v0.9.0-dev-490+gf96fb23de curl version

Curl manual says the following for error code 22:

HTTP page not retrieved. The requested URL was not found or returned another error with the HTTP error code being 400 or above. This return code only appears if --fail is used.

With which engine are you experiencing the problem?

I'm sorry, I forgot to share my config:

require 'pantran'.setup({
  default_engine = 'deepl'
})

Now the thing that stood up to me is that although docs specify deepl as a valid engine, running :lua =vim.tbl_keys(require("pantran.engines")) lists only { "apertium", "google", "yandex", "argos" }, does that have to do with issue, maybe?

[potamides]

Did you set up an API key? For DeepL to work you need to create an API key.

You are right, I missed that. Thank you!
