Content placeholder not found in template.

Error message

Content placeholder not found in template.

What it means

Thrown by parseTemplate when the supplied HTML template string does not contain the content placeholder comment (default <!--vue-ssr-outlet-->). The template renderer splits the page around this marker to inject server-rendered markup; a template lacking it cannot be used for SSR output insertion.

Solutions

  1. Add <!--vue-ssr-outlet--> inside <body> of the HTML template where the app should mount
  2. If a custom placeholder was configured, ensure the template contains exactly that string
  3. Confirm the correct template file is being loaded and not a stripped/minified variant
