Error 403 - Client not found - Attachment download

[Gregor Ulbricht]

Hallo,

i try to download attachments from the confluence sides. With this REST Api Call (https://developer.atlassian.com/cloud/confluence/rest/api-group-content---attachments/#api-api-content-id-child-attachment-get) I can get all attachments on a side. This works as expected.

When I now try to download a attachment with the provided Link (seeing Answer: https://community.atlassian.com/t5/Confluence-questions/How-to-download-a-file-attached-in-confluence-page/qaq-p/650334) I'll get the following error:

status: 403,
text: '{"error":{"code":"Forbidden","title":"Client not found","href":"https://api.media.atlassian.com#UnauthorizedError"}}', method: 'GET'

 I also tried to access the link manually and with wget on Powershell there it works as expected and I get the file.

Node.js Superagent Request with Error:

superagent.get(fileURL).end((err: any, res: any) => {
    if (err)
       console.log(err);
    console.log(res);
});

Powershell wget Command without Error:

wget "https://api.media.atlassian.com/file/.../binary?token=...&name=...&max-age=..."

Powershell Result:

Thanks for your help,

I was a bug in Connection with the node Plugin superagent and the proxy server connection.

In almost every case it works, when there is no proxy to set an empty proxy for superagent. When you try to download some files you can't set an empty proxy, either you set an active proxy or you set no proxy otherwise the above subscribed error occurs.
