How do you extend templates in Leaf using the #extend and #export tags in leaf?

Question

The Leaf documentation doesn't seem to be working for me I can't figure out why.

child.leaf

#extend("index"):
    #export("hello"):
        <p>Welcome to Vapor!</p>
    #endexport
#endextend

index.leaf

<!-- Backend Projects -->
<div class="seciton-label">
    <h3>#(.backendCollection.title)</h3>
</div>
  
#import("hello")
 
<!-- Backend Card -->
#for(card in .backendCollection.collection):
<div class="greeting-card">
    <a href=#(card.url)>
        <h3>#(card.title)</h3>
    </a>
    <p> #(card.description) </p>
</div>
#endfor

The following image is the result I get in localhost

Request result running the vapor server on localhost

Please help - I can't find solutions to this issue. No response from forums.swift.org

Tried removing the import key
Removing quotes
I saw individuals using the following format in older versions of Vapor. This did not work for me either.

<!-- I tried the following format for the extend and export blocks -->

#extend("index") {
    #export("hello") {
        <p>Welcome to Vapor!</p>
    }
}

I'm trying to be able to extend the leaf templates and understand why the html does not render.

This works and does something similar to what you want.

This is my 'template' (heavily simplified here), called Base.leaf :

<!DOCTYPE html>
<html>
   <head>
      <title>#(title)</title>
   </head>
   <body>
        #import("body")
   </body>
</html>
#extend("Build/Message")
</body>
</html>

The extend of Build/Message above behaves simply like an include.

Then I use it in a form called Login.leaf here:

#extend("Build/Base"):
#export("body"):
<form method="POST" action="/log-in">
    <label for="email">Email</label>
    <input type="text" name="email" required>
    <label for="password">Password</label>
    <input type="password" name="password" required>
    <button class="btn-success">Log-in</button>
</form>
#endexport
#endextend

I then use the `Login.leaf' in a render such as:

let context = ["title": "Log in", "version": C.Msg.Version, "message": request.getMessage()]
return try await request.view.render("Form/Login", context)
