Jina Reader doesn't abide by viewport

[norvalbv]

Hi, i'm adjusting my viewport configuration and testing Jina against my own site; all events are being tracked in Mixpanel automatically. I've got the following request:

curl https://r.jina.ai/ \
  -H "DNT: 1" \
  -H "X-No-Cache: true" \
  -H "X-Return-Format: markdown" \
  -H "X-Timeout: 10" \
  -H "X-Token-Budget: 20000" \
  -H "X-Wait-For-Selector: body" \
  -d @- <<EOFEOF
  {
    "url": "https://www.<redacted>.com/",
    "viewport": {
        "width": 1280,
        "height": 800
    }
  }
EOFEOF

Upon checking my mixpanel, the event auto-generated is as follows:

{
  "event": "page_view",
  "properties": {
    "time": 1742299518.225,
    "$browser": "Chrome",
    "$browser_version": 134,
    "$os": "Linux",
    "$screen_height": 600,
    "$screen_width": 800,
    "Path": "/",
    "mp_country_code": "US",
    "mp_lib": "web",
// rest omitted
  }
}

As you can see the screen width and height aren't the same as the ones given in the request. How do I solve this?

Hi @norvalbv

I'm not sure how "mixpanel" detects screen width or height, but Reader should have a default viewport of 1024x1024, even if the viewport settings are not working.

You can verify the viewport settings by requesting with x-return-format: screenshot and check the width/height of the output image.
