Additional comments

I am using 3.0.0-next.17 because of this issue - #968

since I use svelte:boundary in my app I have to use 3.0.0-next.5 or higher

Thanks for posting this issue.

You need to configure it like this:

	{
-		files: ['**/*.svelte'],
+		files: ['**/*.svelte', "**/*.svelte.ts"],

		languageOptions: {
			parserOptions: {
				parser: ts.parser
			}
		}
	},

The second error was fixed by upgrading to v3.0.0-next.18.
