resources.GetRemote with front matter unsupported protocol scheme ""

[Vladimir_dev]

Hello. I have some error.

+++
mainImg = "https://imgopt.pages.dev/assets/xrpl-grants-crypto-projects_original.jpg"
+++

single.html

{{ $url := "https://imgopt.pages.dev/assets/xrpl-grants-crypto-projects_original.jpg" }}
{{ $url_par := .Params.mainImg }}
{{ with resources.GetRemote $url_par }}
        <img
          class="object-cover"
          src="{{ .Permalink }}"
          alt="{{ .Params.altMainImg }}"
          title="{{ .Params.titleMainImg }}"
          loading="lazy"
          decoding="async"
          {{/* crossorigin="anonymous"
          sizes="(max-width: 768px) 100vw, (max-width: 1024px) 50vw, 33vw"
          srcset="small.jpg 500w, medium.jpg 768w, {{ .RelPermalink }} 1024w"           */}}
        />
        {{ end }} 

When I use $url with a string, it works fine, but when I use $url_par, I get an error.

What is .Params.mainImg? Does that value exist on every page?

@jmooring

Does that value exist on every page?

So…?

[Vladimir_dev]

Yes. I created new branch, saved and del all content and I have only one post. I changed mainImg with all languages and have an error too

[jmooring]

I’m pretty sure you missed something. When a page doesn’t have a mainImg param the value is “”, hence the error. Learn to code defensively:

{{ with .Params.mainImg }}
  {{ with resources.GetRemote . }}

  {{ end }}
{{ end }}

[Vladimir_dev]

Problem was with empty single.html file in my content when I test theme
I deleted it and code works fine

[jmooring]

Regardless, code defensively.
