How to handle Slatejs document in Nxut-Keystone5

I have a Nuxt-Keystone project in which have a list(keystone schema) called Post with post body as content type which is a slatejs document

Problem

I tried many way to output the post body (Document), it didn't work for me.

Anybody know how to handle slatejs docs in a Vue component ? Please give me a hand.
