❌ IPX error:

{
  "error": {
    "message": "[400] [IPX_INVALID_IMAGE] Cannot parse image metadata: /images/icons/glasses.svg"
  }
}

Describe the bug

I'm working on a nuxt site with uses nuxt content and in those content files I'm referencing images in a normal markdown way:

[ ![Glasses Icon](/images/icons/glasses.svg) ]

nuxt content then uses nuxt image(and by extension IPX) to transform the that into the final html:

<img data-nuxt-img="" srcset="/_ipx/_/images/icons/glasses.svg 1x, /_ipx/_/images/icons/glasses.svg 2x" onerror="this.setAttribute('data-error', 1)" alt="Glasses Icon" src="/_ipx/_/images/icons/glasses.svg" data-error="1">

1. If I'm loading the normal glasses.svg file, everything works like normal and the svg image renders on the page.
2. If I then go update the glasses.svg file to have <symbol>/<use> tags and then reload the page.
   • The svg image does not render, instead displaying just the alt text Glasses Icon in it's place.
   • If I go directly to the image(/_ipx/_/images/icons/glasses.svg) it returns this error json:

{
  "error": {
    "message": "[400] [IPX_INVALID_IMAGE] Cannot parse image metadata: /images/icons/glasses.svg"
  }
}

Additional context

For some reason if I have this extra commented out line at the top of the glasses.svg file with <symbol>/<use> tags the IPX error goes away:

Start by reproducing the issue through the IPX endpoint using the two SVG variants in the report: the plain SVG and the version containing and . Trace the SVG metadata parsing path used by IPX and compare its behavior for both inputs. Done means the symbol/use SVG is accepted without IPX_INVALID_IMAGE while the existing SVG behavior remains intact.
