V13.3.0 + UF V13.1.2 All forms submit successfully on local dev machine. Site changes are deployed via a GitHub action. Forms are put live via uSync.Forms. When submitting forms on the Production environment all of the forms situated in a UF folder fail immediately with :-

InvalidOperationException: The 'Microsoft.AspNetCore.Mvc.ViewFeatures.Infrastructure.DefaultTempDataSerializer' cannot serialize an object of type 'Umbraco.Forms.Web.Models.FormViewModel'.

I have no idea why. The error message seems it would apply to any and all forms. The forms in question all have a "Go to page" set on their "Message on submit" workflows. The page they "Go to" exists on live and shows correctly on the live forms' workflow settings. All forms in the forms root submit fine. All the appropriate files are on live, i.e. themes, email forms, etc. Please advise.

Trying to figure out which property editor would suit this situation best. It's a Table, however the design needs it to be laid out completely differently for Mobile. So can't simply output an HTML table. Need the json data to represent a table format but in rows / cells:

{
  "Row": {
    "0": "Row 0 Cell 0 data",
    "1": "Row 0 Cell 1 data"
  },
  "Row 1": {
    "0": "Row 1 Cell 0 data",
    "1": "Row 1 Cell 1 data"
  }
}

However the user can create tables with various numbers of columns, so for a 4 column the data needs to look like this:

{
  "Row": {
    "0": "Row 0 Cell 0 data",
    "1": "Row 0 Cell 1 data",
    "2": "Row 0 Cell 2 data",
    "3": "Row 0 Cell 3 data"
  },
  "Row 1": {
    "0": "Row 1 Cell 0 data",
    "1": "Row 1 Cell 1 data",
    "2": "Row 1 Cell 2 data",
    "3": "Row 1 Cell 3 data"
  },
}

Any good ideas for the property editor in this instance? Simple way would be for them to have a different property editor for tables with 1, 2, 3 or 4 columns. However feels like there should be a better way. Thanks!

I'm currently testing Backoffice app. Since it's still in work, there is a lot of features that are not working and I'm aware that I will need to update my application periodically. Does anyone know how can I update my project to get the latest features? (should I just git pull each time?) How would should I maintain my code in the repository, while still giving myself an option to update a repository with latest changes?

Hey Umbraco Community, I am currently working on importing products into Umbraco. Essentialy, I need to make an API call (which returns JSON data) to fetch some base information for products (such as SKU, Name, Price). Once I've obtained the data, I want to automatically generate Product nodes under my general container node for Products, and populate some of their properties with the data that I retrieve from the API. Additionally, I also want to update Products at scheduled intervals (for example, weekly). What I really wanted to ask you is what the best approach for this would be? What types of classes should I create to streamline this workflow? I found this article which seems to address my requirements, however, given that the article is 6 years old, I wanted to check with you in the community if there is a more modern way of doing this. Thanks in advance! https://skrift.io/issues/importing-external-data-as-content-in-umbraco/

Just upgrading a website from v10 to v13 and getting the error "XPathValue must be an XPathNavigator or a string". Whilst I understand XPath is obsolete and being removed in v14, I'd expect this to still work in v13. Here's the line of code within a partial view causing the error:

var BlogItems = Umbraco.ContentAtXPath("//blogItem").OrderByDescending(x => x.Value<DateTime>("newsDate"));

No doubt others may see this same issue with their upgrades if using a similar implementation. Any clues as to what I can do to resolve the error? Thanks! 🙂

Hello. I have implemented the member login and register functionality from the Umbraco Docs (Link to docs). The docs didn't show the remember me button, but it is present when you use the Macro snipit. But no matter how many docs or forum posts I read, I can't find a way to change the default timeout for the remember me button. Code below shows the Macro snippet that Umbraco creates.

cs
@using (Html.BeginUmbracoForm<UmbLoginController>(
    "HandleLogin", new { RedirectUrl = loginModel.RedirectUrl })) {
 <h4>Log in with a local account.</h4>
        <hr />
        <div asp-validation-summary="ModelOnly" class="text-danger"></div>
        <div class="mb-3">
            <label asp-for="@loginModel.Username" class="form-label"></label>
            <input asp-for="@loginModel.Username" class="form-control" />
            <span asp-validation-for="@loginModel.Username" class="form-text text-danger"></span>
        </div>
        <div class="mb-3">
            <label asp-for="@loginModel.Password" class="form-label"></label>
            <input asp-for="@loginModel.Password" class="form-control" />
            <span asp-validation-for="@loginModel.Password" class="form-text text-danger"></span>
        </div>
        <div class="mb-3 form-check">
            <input asp-for="@loginModel.RememberMe" class="form-check-input">
            <label asp-for="@loginModel.RememberMe" class="form-check-label">
                @Html.DisplayNameFor(m => loginModel.RememberMe)
            </label>
        </div>
        <button type="submit" class="btn btn-primary">Log in</button>
    }

It's the

<input asp-for="@loginModel.RememberMe" class="form-check-input">

I'm looking at. EDIT: I have seen that you can create a global cookie in appsettings, but I need remember me to be able to be turned on or off. EDIT: I'm using

UmbAlternativeLoginController

What I would like to ask is, how do I change the default timeout for the member that is signing in, with the remember me button?

Anyone know how to set a Machine Key in Umbraco 13 that matches Umbraco 8? I'm trying to import Users from V8 a clean V13 using uSync Complete and People Edition> The Docs say "As a result you should ensure that any Umbraco instances where you wish to sync members (users?) should have the same machineKey value in their web.config files." Simple enough I thought, but obviously v13 doesn't use a web.config file and I'm strugging to figure out how to set a machine key successfully

Hi all, I need to implement a Single Sign Off function for Members, on a load balanced site (1 edit app, 2 frontends). The SSO service we use has added new requirements that require us to have an API endpoint that can be hit to request a user logout. The problem is, we currently don't have any kind of distributed user session storage, and rely on the Application Gateway affinity cookies to keep a signed in user on the same frontend server. (which works very well) Therefore I now need to implement some kind of distributed user session storage and, after some research, it seems like redis is probably the way to go. I found this blog post, about using Azure Redis Cache to store user sessions, which looks quite promising: https://dev.to/garpunkal/umbraco-9-azure-cache-for-redis-3ipi But it seems too easy, surely that's not all there is to moving user sessions to redis? Has anyone else implemented something similar?

Package developers.. I see I can use

json
      "Unattended": {
        "PackageMigrationsUnattended": false

to set all packages to have to migrate via the backoffice. Is there a settings on the

migrationBase

perhaps that I can use to just set that my package has to via the backoffice, and not unattended?

I know I can use

Model.Value<string>("alias", fallback: Fallback.ToAncestors)

but is there a straightforward way to call ModelsBuilder properties with a fallback parameter? I could change the generated class, but I'm hoping if there's a more permanent option. Incidentally I tried using

Model.ValueFor(x => x.Alias, fallback: Fallback.ToAncestors)

as per [the docs](https://docs.umbraco.com/umbraco-cms/fundamentals/design/rendering-content), which would be fine, but it throws an error (when falling back to an ancestor): NotSupportedException: Fallback PublishedValueFallback does not support fallback code '3' at element level.
