Usando LightDarkImg gera erro

[NateDhaliwal]

Ao usar <LightDarkImg />, recebo um erro intrigante que não indica a causa do problema.

Erro:

Meu código:

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

Os métodos são os seguintes:

  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; // Se nenhum logo em modo escuro for carregado, use o logo normal
    }
  }

Estou registrando tudo no componente LightDarkImg mencionado (duplicado no meu sistema de arquivos), e as URLs das imagens são impressas corretamente. Elas até são exibidas corretamente em tags <img>.

Alguma ideia? Obrigado.

Você pode compartilhar o arquivo completo, incluindo as importações?

Eu recomendaria reduzir o código pouco a pouco até que funcione. Por exemplo, o erro vem do {{#if? Do (and? Ou de um dos getters?

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

@NateDhaliwal

<div>

Este trecho parece suspeito. Envolver algo entre parênteses em um template do Ember faz com que seja tratado como um helper (ou seja, uma função). Portanto, acho que você quer remover um nível de colchetes aí:

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

A propósito, você está desenvolvendo contra uma instância de produção aqui? Se você usar uma instância de desenvolvimento em vez disso, você obterá uma mensagem de erro muito melhor.

[NateDhaliwal]

Obrigado pela dica. Funciona normalmente, em outro branch , mas farei isso de qualquer maneira. Usando produção, mudarei para desenvolvimento e verei se isso ajuda.

[NateDhaliwal]

Huh, sem mais erros depois de fazer essa alteração. Talvez tenha sido isso. Obrigado pela ajuda; <LightDarkImg /> funciona perfeitamente agora!
