Hcaptcha request error 400

[aigottfriadhelp]

Hello, I am solving hcaptcha using node.js 20. I constantly get this error, while api data is passed correctly (I can withdraw the balance) and the parameters are definitely transferred correctly - the site key and the URL of the page on which the captcha is located. Error 400, with and without proxy parameter.
Data passed:
{"type":"hcaptcha","sitekey":"correct_sitekey","url":"correct_url","proxy":{}}
Error:
InvalidRequestError: Invalid request

That proxy object appears to be malformed, can you share your exact call of the function?
