Adaptive Cards Cannot add description property

Question

I am trying to build Image Adaptive Card for the first time, I thought "Description" Property can be added how it can added in the normal web part SPFx. I was wondering how to add "Description" to "ICardParameters"

CardView.ts

  public get data(): IImageCardParameters {
    return {
      primaryText: strings.PrimaryText,
      imageUrl: require('../assets/MicrosoftLogo.png'),
      title: this.properties.title,
      description: this.properties.description --- Type '{ primaryText: string; imageUrl: string; title: string; description: string; }' is not assignable to type 'ICardParameters'. Object literal may only specify known properties, and 'description' does not exist in type 'ICardParameters'.
    };
  }

PropertyPane.ts

PropertyPaneTextField('description',{
                  label: strings.Description,
                  multiline: true,
                  rows: 5
                })

Answer 1

As per the Microsoft official documentation of IImageCardParameters interface it has two properties:

• imageUrl
• primaryText

Also, this interface extends the IBaseCardParameters interface which has below proerties:

• iconAltText
• iconProperty
• title

So, you can only specify above known properties and cannot use 'description' as it does not exist in the interface type you are using.

Answer 2

According to my research and testing, we cannot add "Description" . IImageCardParameters interface only has imageUrl and primaryText properties. Thanks for your understanding.
