Can't getPagedMembers over installation

[lilianmisser]

Hi, I am working on a Teams bot for my organization that sends notification to user when it is called through an azure function.

We have a teams app using [email protected] that was made 2 years ago and that we can't maintain so we decided to use the latest version of teamsfx (v4). I use the Microsoft Agent 365 toolkit extension in VSCode to generate the boilerplate for a notification bot usable through Azure functions.

In this very basic example I am trying to retrieve user email using the getPagedMembers functions and I keep getting the same logged error without my code crashing :

Boilerplate with the added getPagedMembers:

const httpTrigger: AzureFunction = async function (
  context: Context,
  req: HttpRequest
): Promise<void> {
  // By default this function will iterate all the installation points and send an Adaptive Card
  // to every installation.
  const pageSize = 100;
  let continuationToken: string | undefined = undefined;
  do {
    const pagedData = await notificationApp.notification.getPagedInstallations(
      pageSize,
      continuationToken
    );
    const installations = pagedData.data;
    continuationToken = pagedData.continuationToken;

    for (const target of installations) {
      const members = await target.getPagedMembers(100, undefined);

      console.log("members", members);
      ...
    }
   } while (continuationToken);

  context.res = {};
};

Error displayed:

Executing 'Functions.notifyHttpTrigger' (Reason='This function was programmatically called via the host APIs.', Id=0dbe3a42-e9d4-4407-853c-c781de65ce03)

Value of members : members { data: [], continuationToken: '' }

By the way I tried different ways of retrieving members using botbuilder TeamsInfo.getMember and using @microsoft/agents-hosting-teams TeamsInfo.getMember but kept getting the same unclear error
