VS Code Dialogue Preview Compilation Failed

[jellbot-dev]

What is the current behavior?

Attempting to preview a default, simple .yarn file in VS Code results in the dialogue preview pane displaying Compilation Failed: [...]/Yarn/Script.yarn:2:0 - Nodes must have a title (Despite the only existing node having a title)

Please provide the steps to reproduce, and if possible a minimal demo of the problem:

Create a new .yarnproject and .yarn script filled with the default:

title: Start
---
This is an example of a Yarn Spinner script. Write your dialogue here!
===

When you open the dialogue preview (via either the "Preview Dialogue" or the "Play this node" button), an error is given saying the node doesn't have a title.

What is the expected behavior?

It compiles successfully and displays the dialogue preview.

Please tell us about your environment

• Operating System: Linux Mint 22.3 - Cinnamon 64-bit

The encoding of my .yarn file defaulted to UTF-8 with BOM which had the same error so changing it to just UTF-8 fixed it for me
