Why RESP API returns " Error 400. The request has an invalid header name"?

I'm Trying to access Azure's OpenAI chat completions REST API with SAS proc http. Model is gpt-4 (0613). Access url I'm using is: 

https://RESOURSE.openai.azure.com/openai/deployments/DEPLOYMENT/chat/completions?api-version=2023-07-01-preview

Without headers answer from Azure is:

 "{"error":{"code":"401","message":"Access denied due to invalid subscription key or wrong API endpoint. Make sure to provide a valid key for an active subscription and use a correct regional API endpoint for your resource."}}"

After adding the key header the answer is: 

{
  "error": {
    "message": "Invalid Content-Type header (application/x-www-form-urlencoded), expected application/json. (HINT: If you're using curl, you can pass -H 'Content-Type: application/json')",
    "type": "invalid_request_error",
    "param": null,
    "code": null
  }
}

So far so good, I guess.

Then I add header according to the error message:

Content-Type: application/json

And the answer is:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<HTML><HEAD><TITLE>Bad Request</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Bad Request - Invalid Header</h2>
<hr><p>HTTP </p>
</BODY></HTML>

If I add some random header instead of Content-Type, just so I have two headers:

api-key:key
connection: keep-alive

Answer is same as with just the key:

{

  "error": {

    "message": "Invalid Content-Type header (application/x-www-form-urlencoded), expected application/json. (HINT: If you're using curl, you can pass -H 'Content-Type: application/json')",

    "type": "invalid_request_error",

    "param": null,

    "code": null

  }

}

All the example codes and even the error message says I should add 'Content-Type: application/json'.

But why that gives the: " Error 400. The request has an invalid header name."?

I'm not even sure if message body is correct:

'{
		"role": "user",
		"content": "Say hi!"
	}'

But the error is about the headers, so I don't think the message body is the reason for invalid header -error.

    We are getting exactly the same issue, we are obviously send the Content-Type: application/json and the body is json encoded array, yet we get a response saying we are sending application/x-www-form-urlencoded nuts!
