   May I ask what are you downloading (url example)? Did it work with older ayon api or server?

   This might resolve the issue, but I can't test it #295 .

   Yeah, it worked with the api version 1.2.6 (on 1.13.6 server as well)

   it was a note attachment something similar to:

   ayon_api.download_file(f"projects/{self._project_name}/files/{attachment_id}", "/path/to/destination.jpg")

   I tried running my tests using the pull request revision as my ayon-python-api source in uv. and I think it pulled it in correctly. However I got the same key error. It's weird that this request object does not have content-length in it however it does have these keys

   {'Server': 'openresty', 'Date': 'Mon, 05 Jan 2026 14:38:33 GMT', 'Content-Type': 'text/html; charset=utf-8', 'Transfer-Encoding': 'chunked', 'Connection': 'keep-alive', 'cache-control': 'no-cache', 'X-Served-By': 'ayon-dev-url', 'Content-Encoding': 'gzip'}

   Ah, the request is doing something wonky. The contents of the response are:

   '<!DOCTYPE html>\n<html lang="en" data-color-mode="dark">\n  <head>\n          <script type="module" src="/assets/hostInit-CB81M3mg.js"></script>\n        \n    <meta charset="UTF-8" />\n    <meta name="viewport" content="width=device-width, initial-scale=1.0" />\n    <meta name="theme-color" content="#2c313a" />\n    <meta name="description" content="" />\n    <meta name="robots" content="noindex" />\n    <title>AYON</title>\n    <!-- FALLBACK FAVICON -->\n    <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">\n    <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">\n    <link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">\n    <link rel="manifest" href="/site.webmanifest">\n    <link rel="mask-icon" href="/safari-pinned-tab.svg" color="#00d7a0">\n    <meta name="msapplication-TileColor" content="#00aba9">\n    <!-- FALLBACK FAVICON -->\n    <script type="module" crossorigin src="/assets/index-BoWUAhJM.js"></script>\n    <link rel="stylesheet" crossorigin href="/assets/index-Dsy2eoNX.css">\n  </head>\n  <body>\n    <noscript>You need to enable JavaScript to run this app.</noscript>\n    <div id="root"></div>\n  </body>\n</html>\n'
   

   so it seems the request is failing.

   and the kwargs for the 1.2.7 request (from with get_func(url, **kwargs) as response: fame)

   {'stream': True, 'headers': {'Content-Type': 'application/json', 'x-ayon-platform': 'linux', 'x-ayon-hostname': 'hostname', 'referer': 'http://ayon-dev-url, 'X-Api-Key': '000000apikey0000'}}
   

   however the kwargs for the 1.2.6 request is:

   {'stream': True}
   

   so it's the request itself that's failing

   Ok, let me try.

    Ok, so this is because of fixed bug that was in the download logic. It does not prefill api by default in endpoint. If you pre-pend api/ to the url it should work.

    ayon_api.download_file(
        f"api/projects/{self._project_name}/files/{attachment_id}",
        "/path/to/destination.jpg"
    )

    EDITED:
    For compatibility with both new and old ayon_api you can use this

    rest_url = ayon_api.get_rest_url()
    f"{rest_url}/projects/{self._project_name}/files/{attachment_id}"
