From 4.9.0: Cannot read property 'split' of undefined

Upgrading from 4.8.0 to 4.9.0 I get this:

I'm using SvelteKit@1.0.0-next.162.

Hey, @frederikhors 👋 Fixed on 4.9.1, thanks for the report!

Out of curiosity, are you defining typescript as the default language?

[frederikhors]

Out of curiosity, are you defining typescript as the default language?

Yes, I'm using SvelteKit with TS. Are you asking this?

[kaisermann]

Not exactly, sorry! I meant if you are using typescript without writing lang="ts" on your script tag 😅 Can you share the top of the script tag that caused the error? I'm trying to write a test for this issue.

[frederikhors]

Nope, I'm using <script lang="ts">.

Is there a way I can set it to default?

[dummdidumm]

No (you shouldn't). So what's the file content with which this error is reproducible?
