File POST works in VS Code ext. but not this one.

Describe the bug
POST call to upload a file is working in the VS Code extension but not in this one.
Does not appear to be replacing the @values.

Response in Visual Studio Pro 2022 (64-bit) v17.1.5 is:
"An invalid request URI was provided. The request URI must either be an absolute URI or BaseAddress must be set."

To Reproduce
@hostname = localhost
@PORT = 44388
@host = {{hostname}}:{{port}}
@baseurl = https://{{host}}

@boundary = ----demoBoundary
@ContentType = multipart/form-data; boundary={{boundary}}

POST {{baseurl}}/sendfile HTTP/1.1
Content-Type: {{contentType}}

--{{boundary}}
Content-Disposition: form-data; name="file"; filename="jellyfish.jpg"
Content-Type: application/octet-stream

< ./files/pexels-cristian-muduc-10027304.jpg
--{{boundary}}--

Expected behavior
The "[FromForm(Name = "file")] IFormFile file" is seen by the endpoint. It is valid when sent from VS Code, but null when sent by this extension.

If I hard code the variables, I get an "HTTP/1.1 400 Bad Request" with a "File not sent" message.

I have a similar issue. When posting the exact request in VS Code, it works fine. When using the Rest Client for Visual Studio on the same machine I get a 401 Unauthorized error.
