Describe the bug

I'm getting below error when I log as below

const reqBody = await event.request.formData();
log.info(reqBody)

event is https://kit.svelte.dev/docs/types#public-types-requestevent.
but it works fine if I do log.info(JSON.stringify(reqBody))

TypeError Cannot read properties of undefined (reading 'reduce')
