TypeError: Cannot read properties of undefined (reading 'source')

Describe the bug

When trying to autocomplete component properties I get this error:

TypeError: Cannot read properties of undefined (reading 'source')
    at CompletionsProviderImpl.getCompletions (c:\Users\e-svetinar\.vscode\extensions\svelte.svelte-vscode-105.22.1\node_modules\svelte-language-server\dist\src\plugins\typescript\features\CompletionProvider.js:136:34)

As far as I could debug it I found that this pull #1609 introduced this bug.
Error is happening in line

language-tools/packages/language-server/src/plugins/typescript/features/CompletionProvider.ts

Line 274 in 0bffac8

if (c.data.source?.includes('.svelte-kit/types')) {

Reproduction

I am using "carbon-components-svelte" maybe this is the problem since it works OK with my own components.

I created a github repo which if you try to autocomplete inside +page.svelte on a Header component there should be an error in output but if you try to autocomplete inside Component it's OK.

Expected behaviour

Autocomplete should actually suggest useful suggestions.

System Info

• Windows
• VSCode (1.71.0)
• Svelte extension (105.22.1 or 105.22.0) It works OK in 105.21.0

Which package is the issue about?

svelte-language-server
