template functional in <template> not working when render function does

[flozero]

• I confirm that this is an issue rather than a question.

Bug report

Steps to reproduce

Use this:

<template functional>
</template>

Register the component with plugin-register-component

What is expected?

It should work as development.

What is actually happening?

You got this errror when you are trying to build the documentation

TypeError: _vm._ssrNode is not a function
    at render (src/components/T.vue?8d6b:1:46)

Other relevant information

When you run the dev docs command it working.
Or if you are using rendering function in script and adding functional: true. The build working in this case too.

Same issue in my side. I found a similar issue ever been closed vuejs/vue-loader#1170. I guess something wrong with the coordination between the vue-template-compiler and SSR render version used by VuePress 1.x.

Just use normal component can work around.

How do you call your functional component? if with lazy import (example) :
components: { example: () => import('@/components/example.vue') },
it can generates this error !

TypeError: _vm._ssrNode is not a function
    at render (src/components/T.vue?8d6b:1:46)

Need to import it with no lazy import.
