Reproduction

Passing an H3 event from an API eventHandler to a function in the server/utils directory causes this error:

Cannot read properties of undefined (reading 'messages')

Describe the bug

My function where the error originates:

Looking at the stack trace at the bottom I think I've manage to figure out why it's erroring with this.

Firstly the localeDector is called here with 1 param (event)

This seems to be calling this localeDetector function which requires the i18nContext context as it's second param.

Which is why this line fails:

await loadAndSetLocaleMessages(locale, localeLoaders, i18nContext.messages);

because i18nContext is undefined.
