Since update from 0.21.4 getting "Invalid Payload: Error: Request failed with status code 400"

[Shaquu]

Describe the bug

Since I updated from 0.21.4 I am getting rejections from my UniFi server.

As an axios client, I receive Invalid Payload: Error: Request failed with status code 400
On the server, I see [https] 4ms 404 POST /auth/login SyntaxError: Unexpected end of JSON input

I have compared 0.21.4 request log to 0.24.0 and nothing has changed.

To Reproduce

To reproduce you need UDM machine and node-red node installed https://github.com/NRCHKB/node-red-contrib-unifi-os/tree/0.5.3

Axios.interceptors.request.use(config => console.log(config))

{
    headers: {
        common: {
            Accept: 'application/json, text/plain, */*'

        head: {},

        },
        put: {

        patch: {

}

Expected behavior

It should work :)

Environment

• Axios Version (0.21.4 is working, >0.21.4 and <= 0.24.0 is failing)
• Node.js Version 16.11.0
• OS: Windows 11, Raspbian

Additional context/Screenshots

nah

I just noticed.
On 0.21.4 Content-Length is correct but on 0.22.0+ is not

Caused by #2880

@Shaquu Is this fixed? I had similar issues with 0.24.0 and 0.25.0. How did you fix this?

[Shaquu]

@vojvodics For some reason I had few lines of code generating length header manually.
I removed it and let axios handle it and it started to work!

If you still have that problem and you have a steps etc I could help to debug.

Thanks for offering help, I'll try to make a reproduction repo
