] | Vue Quill is expecting you to define [your custom toolbar](https://vueup.github.io/vue-quill/guide/toolbar.html#custom-toolbar-container). That error happens when you define a custom toolbar selector '#toolbar' but don't actually put the toolbar anywhere (it is looking for an element with an id of "toolbar"). | The main reason to this could be due to the fact that when ssr is used, Nuxt tried to render in server-side but it does not exist.
Moreover, I am not really sure if quill will support Vite at the moment so I suggest using packages like vue3-quill-editor-vite. |
