Chapter 8 Online Section http linebreaks not working

[Pip1987]

*** This is a Visual Studio issue see comment below.***
I'm working through chapter 8's online section for odata when I try the request

###
GET {{base_address}}categories/
  ?$select=CategoryId,CategoryName

it returns

{
  "@odata.context": "https://localhost:5084/catalog/$metadata#Categories",
  "value": [
    {
      "CategoryId": 1,
      "CategoryName": "Beverages",
      "Description": "Soft drinks, coffees, teas, beers, and ales",
       .......

and I have an error stating '?$select=CategoryId,CategoryName' is not a valid http header. Expecting a valid http header or a blank line to separate the header section from the request body.
when I run the request as a single line GET {{base_address}}categories/?$select=CategoryId,CategoryName the output is correct.

{
  "@odata.context": "https://localhost:5084/catalog/$metadata#Categories(CategoryId,CategoryName)",
  "value": [
    {
      "CategoryId": 1,
      "CategoryName": "Beverages"
    },
    {
      "CategoryId": 2,
      "CategoryName": "Condiments"
    },
    ...

I've tried both with and without indent on the the ?$select line.

P.S.
And I know I've done a few issues, but honestly this book and the previous have been really helpful on learning new things and how to do other things better with c#. I've been really enjoying the books.

So looking over http file documentation on the Microsoft website for un related issue I found this https://learn.microsoft.com/en-us/aspnet/core/test/http-files?view=aspnetcore-8.0#unsupported-syntax stating that multi line requests don't work. Apparently these will work in Visual Studio code though.

Thanks! I have added an errata item for this:

p.s. I'm happy to hear that you're enjoying the books. I really appreciate you taking the time to raise these issues that help everyone. Keep them coming!

p.p.s. I'm busy writing the third book and have deadlines every Monday for new chapters so I don't have as much time as usual to investigate issues but quick ones like these I try to get to.
