Sharepoint: Banner Image URL takes me to This site can't be reached

Question

Hi,

In the default site pages library I have site pages with a banner image uploaded, tried everything, from the site or locally, and as you can see from the image below, the image is just a broken link that when clicked it gives me the err_invalid_response.

For the default Home.aspx , the banner image is in /sites/layout.../sitepagesthumbanil.png
While any page I create and then upload a banner, the image is in /sites/getpreview.ashx?path...
It's like it doesn't find the image?

Ultimately, what I need this image preview is because I'm using powerapps to display the articles in a gallery, and for the image whenever I use ThisItem.BannerImageUrl or ThisItem.Thumbnail.Large , a white images gets displayed, so I'm open to other ways to display the image of site page.

Any tips?

Hi @FrankM
Per my test, banner image URL of modern page is generated automatically after we upload a banner image.

If you want to display the url into image, we could use the following column formatting with Advanced mode:

{
"$schema": "http://columnformatting.sharepointpnp.com/columnFormattingSchema.json",
"elmType": "div",
"children": [
{
"elmType": "img",
"attributes": {
"src": "@currentField",
"title": "@currentField"
},
"style": {
"position": "relative",
"top": "50%",
"left": "50%",
"width": "48px",
"height": "auto",
"margin-left": "-50%",
"margin-top": "0%"
}
}
]
}

As a result: the url turn into image.
