I'm customizing Adaptive Card to display generative answer's citations because Virtual Agent in Teams does not show citations well.

My current code is this.

{
    type: "AdaptiveCard",
    '$schema': "http://adaptivecards.io/schemas/adaptive-card.json",
    version: "1.5",
    body: [
        {
            type: "Container",
            items: ForAll(Topic.Answer.Text.CitationSources,
            {
            type: "TextBlock",
            text: "[" & Id &"]：[" & Name & "]("&Url&")",
            wrap: true,
            size: "Small",
            weight: "Lighter"
            }
            )
        }
    ]
}

In case the citation link referring to SharePoint Document Library Files or Public Web Sites, this works well.

However, when generative answer refers to SharePoint Modern Page, chat bot returns "SystemError".

In this case, Answer variable is as below.

{
  "Text": {
    "CitationSources": [
      {
        "Id": "1",
        "Name": null,
        "Text": "Page Description",
        "Url": "https://mydomain.sharepoint.com/sites/sitename/SitePages/XXXX.aspx"
      }
    ],
    "Content": "Generative Answer Description [1].",
    "MarkdownContent": "Generative Answer Description [1].\n\n[1]: https://mydomain.sharepoint.com/sites/sitename/SitePages/XXXX.aspx"
  }
}

I think SystemError occurs due to citation item's name is null.

I tried to change the Adaptive Card formula like

text: "[" & Id &"]：[" & If(IsBlank(Name), "Link", Name) & "]("&Url&")",
or

text: "[" & Id &"]：[" & If(IsBlankOrError(Name), "Link", Name) & "]("&Url&")",
the result was same.

Is there any good way to handle null validation.
