connect ECONNREFUSED ::1:7071 when testing Azure Function locally

[Swimburger]

I'm using Azure Functions on macOS to build a Twilio app and I run it using func start (Azure Functions CLI), with the following output

...
Functions:

	IncomingMessage: [POST] http://localhost:7071/api/IncomingMessage

	MessageStatus: [POST] http://localhost:7071/api/MessageStatus

When I try to emulate a webhook request like this:

twilio webhook:invoke http://localhost:7071/api/IncomingMessage --no-signature

I get the following error:

» connect ECONNREFUSED ::1:7071
 » twilio-cli encountered an unexpected error. To report this issue, execute the command with the "-l debug" flag, then copy the output to a new issue here: "https://github.com/twilio-labs/plugin-webhook/issues"

Here's the output with debug logs:

Manually sending an HTTP request using PowerShell works fine:

Invoke-WebRequest http://localhost:7071/api/IncomingMessage `
    -Method POST `
    -Body @{Body="Hello world!"} `
    -ContentType "application/x-www-form-urlencoded"

response is:

<?xml version="1.0" encoding="utf-8"?>
<Response>
  <Message action="/api/MessageStatus" method="POST">You sent: Hello world!</Message>
</Response>

FYI, using the equivalent localhost IP address 127.0.0.1 does work:

twilio webhook:invoke http://127.0.0.1:7071/api/IncomingMessage --no-signature

We discovered that this is not an issue when using Node.js LTS (v16.17.0), but it is an issue when using latest (v18.7.0).
