استخدام LightDarkImg يسبب خطأ

When using <LightDarkImg />, I get a puzzling error that gives no actual indication to the route of the problem.

Error:

My code:

{{#if (and this.logoImg this.darkLogoImg)}}
  <div class="category-logo aspect-image">
    <LightDarkImg
      @lightImg={{this.logoImg}}
      @darkImg={{this.darkLogoImg}}
    />
  </div>
{{/if}}

The methods are as follows:

  get logoImg() {
    if (settings.show_category_logo && this.args.category.uploaded_logo) {
      console.log(this.args.category.uploaded_logo.url);
      return this.args.category.uploaded_logo;
    } else if (
      settings.show_category_logo &&
      settings.show_parent_category_logo &&
      this.args.category.parentCategory &&
      this.args.category.parentCategory.uploaded_logo
    ) {
      return this.args.category.parentCategory.uploaded_logo;
    } else if (settings.show_site_logo && this.siteSettings.logo_small) {
      return this.siteSettings.logo_small;
    } else {
      return false;
    }
  }

  get darkLogoImg() {
    if (settings.show_dark_mode_category_logo && this.args.category.uploaded_logo_dark.url) {
      console.log(this.args.category.uploaded_logo_dark.url);
      return this.args.category.uploaded_logo_dark;
    } else if (
      settings.show_dark_mode_category_logo &&
      settings.show_parent_category_dark_mode_logo &&
      this.args.category.parentCategory &&
      this.args.category.parentCategory.uploaded_logo_dark
    ) {
      return this.args.category.parentCategory.uploaded_logo_dark;
    } else if (settings.show_site_logo && this.siteSettings.logo_small) {
      return this.siteSettings.logo_small;
    } else {
      return this.args.category.uploaded_logo; // If no dark mode logo is uploaded, use the normal logo
    } 
  }

I’m logging everything in the aforementioned LightDarkImg component (duplicated into my filesystem), and the image URLs print correctly. They even display correctly when in <img> tags.

Any ideas? Thanks.

Can you share the full file, including the imports?

I’d recommend reducing the code down bit-by-bit until it works. e.g. is the error coming from the {{#if ? The (and ? Or one of the getters?

I’ll try doing the debugging you suggested, perhaps that can yield some results.

EDIT: Puzzling, commenting out the component still has that error :eyes:, but displaying the URLs in the template is correctly shown.

This bit looks susoucious. Wrapping something in parenthesis in an ember template causes it to be treated as a helper (i.e. a function). So I think you want to drop one level of brackets there:

- <div class="category-title-name" style={{if (not (this.logoImg))
+ <div class="category-title-name" style={{if (not this.logoImg)

By the way, are you developing against a production instance here? If you use a development instance instead, you should get a much better error message.

Thanks for the tip. It works normally, on another branch :eyes:, but I’ll do that anyway. Using production, I’ll switch to development and see if that helps.

Huh, no more error after making that change. Perhaps that was it. Thanks for the help; <LightDarkImg /> works great now!
