Adaptive Card Issue in Microsoft Teams Tabs with teams-js and Angular

Question

We are currently facing an issue with adaptive cards within our Microsoft Teams tabs. This has been functioning correctly since the launch of our application, but we've recently encountered a problem.

When we execute the following code:

dialog.adaptiveCard.open(adaptiveCardDialogInfo, dialogResponse);

The application breaks.

Additionally, the method:

dialog.adaptiveCard.isSupported() //is returning false.

Unfortunately, no explicit error message is displayed, but we do receive an errorCode: 100.

Our current versions are:

@microsoft/teams-js: 2.12.0
@angular/core: ^15.0.0

Has anyone else encountered this issue or can provide some guidance on how to resolve it? Any help would be greatly appreciated.

Sample Code:

      card: JSON.stringify({
        type: "AdaptiveCard",
        body: [
         {
          type: "TextBlock",
          size: "Medium",
          weight: "Bolder",
          text: "Select user(s) in your organization."
         },
         {
          label: "1) Select user(s): ",
          isRequired: true,
          placeholder: "Search and select user(s)",
          type: "Input.ChoiceSet",
          choices: [],
          "choices.data": {
            type: "Data.Query",
            dataset: "graph.microsoft.com/users"
          },
          id: "selection",
          isMultiSelect: true,
          errorMessage: "Atleast one user must be selected."
         },
         {
          isRequired: true,
          label: "2) Message",
          type: "Input.Text",
          size:"Medium",
          placeholder: "Enter your message",
          id: 'message',
          errorMessage: "A message is required."
         },
         {
          type: "Input.Toggle",
          label: "3) Summary",
          title: "Include Summary?",
          valueOn: "1",
          valueOff: "2",
          value: "1",
          id: "sum_type"
         }
        ],
        actions: [
          {
            type: "Action.Submit",
            title: "Cancel",
            associatedInputs: "none"
          },
         {
          type: "Action.Submit",
          title: "Send"
         },
        ],
        $schema: "http://adaptivecards.io/schemas/adaptive-card.json",
        version: "1.4"
       })
    }
    // RUN 
    dialog.adaptiveCard.open(adaptiveCardDialogInfo, dialogResponse);

Thank you!
