V13.1.1 In Views/Partials/Blockgrid/Components... I have an approved colour picker to pick the background colour of a layout. The below code which I've used before on another project throws up a NullReferenceException when it runs. LayoutSettings is set as the Settings Model correctly in the BlockGrid Block Configuration and I've regenerated models and rebuilt. I can't see what else is wrong.

@inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Umbraco.Cms.Core.Models.Blocks.BlockGridItem<Column2, LayoutSettings>>

@{
    string style = "style=\"";
    style += Model.Settings.BackgroundColour is not null ? "background-color: #" + Model.Settings.BackgroundColour + ";" : "";
    style += "\"";
}

<div @Html.Raw(style)>
    @await Html.GetBlockGridItemAreasHtmlAsync(Model)
</div>

If I comment out the line with Model.Settings.BackgroundColour then the page displays. Any suggestions would be appreciated. Thanks.

Can you share what Model.Settings.BackgroundColour is returning?

It's just an empty string

Cache? Glad it's working.
