FirebaseDynamicLinks why doesnt work in app background?

I'm using firebase_dynamic_links in my Flutter App. I did step by step from the document.

  void fetchLinkData(BuildContext context) async {
    PendingDynamicLinkData link =
        await FirebaseDynamicLinks.instance.getInitialLink();
    handleLinkData(context, link);
    FirebaseDynamicLinks.instance.onLink(
      onSuccess: (PendingDynamicLinkData dynamicLink) async {
        handleLinkData(context, dynamicLink);
      },
    );
  }

  void handleLinkData(BuildContext context, PendingDynamicLinkData data) {
    final Uri uri = data?.link;
    if (uri != null) {
      final queryParams = uri.queryParameters;
      if (queryParams.length > 0) {
        String prodId = queryParams["shared"];
        if (prodId != null) {
          Navigator.push(
              context,
              MaterialPageRoute(
                builder: (context) => ProductDetails(),
              ));
          context.read<SupplierRepo>().getProductDetails(prodId);
        }
      }
    }
  }

When I click the link while the application is closed, it does the process correctly, but when I click the link while the application is open in the background, I get this output:

E / FA (26205): Name is reserved. Type, name: event, dynamic_link_app_open
E / FA (26205): Invalid event name. Event will not be logged (FE): dynamic_link_app_open

EDIT [20.01.2021]: I texted firebase support yesterday and they replied to me. The reply is:

"I've tried replicating the issue on my end, and I was also able to reproduce the same error. This looks to be a bug on our end, and I've escalated this to our engineers for deeper investigation.
