Property default does not exist on type 'PostHog'

[bennycode]

I tried to integrate PostHog in my Astro website the following way:

---
import posthog from 'posthog-js';
---

{
  posthog.init('xxx', {
    api_host: 'https://eu.i.posthog.com',
    persistence: 'memory',
    person_profiles: 'always',
  })
}

It crashed my website with the following error:

TypeError: vite_ssr_import_1.default.init is not a function

I changed the code to:

---
import posthog from 'posthog-js';
---

{
  posthog.default.init('xxx', {
    api_host: 'https://eu.i.posthog.com',
    persistence: 'memory',
    person_profiles: 'always',
  })
}

This works now in a live environment but shows me an error in my IDE:

Property 'default' does not exist on type 'PostHog'.

I guess there is something wrong with the default typing?
