Describe the bug

I have initially reported this bug in supposedly same issue: #1154 (comment)

The bug, basically, does not allow you to pre-render the nuxt content (markdown pages). Because every time you try to render them you get the error as in description above.

The issue is not reproducible when you run serve the application from npm run dev command.

Additional context

What I try to achieve is to enable pre-rendering of all pages. So I could host my vue app without the backend server.

It could either be an SPA with pre-rendered pages or a fully static pre-generated website. Currently I am trying to do the former.

Update

After trying few things out it seems like the issue is with the parser or query results.

if you comment out the:

<!--      <div class="card-body">
        <ContentRenderer :value="post"/>
      </div>-->

In DOM you see the following:

And a perfectly rendered list:

And no errors in console.

So what I think is happening is - the nuxt content is querying data and thinks that a perfectly valid data is returned, so he renders it. And when I try to render a markdown specifically - it shows the error as the data in not markdown format (i.e. You should use slots with <ContentRenderer>).

Anyways, I think this is a bug in any case. Error should be shown if data is invalid or missing. And, I still hope that you could provide some examples how to do the pre-rendering properly. And if pre-rendering is not supposed to work then please update the documentation.

Thank you for the issue and description. Generating non-ssr websites is tricky and yet not supported in V2.

I'd suggest using ssr: true until the official support of non-ssr projects. The experience is totally same, expect the first load :)

I'm closing this in favor of #1229.
