I am using SeoToolKit and Umb v13. I have a multi-site setup where staff bios are being shared. I created a shell page that gets the staff member data from an ID on the route. The issue I keep running into is that the SeoToolKit is throwing missing object errors when loading. When I remove the tag helpers, the page will load fine. I am wondering if there is someone who knows the SeoToolKit package better and can tell me how to populate SEO tags from the Umbraco Page Controller.

Hi! Creator of SeoToolkit here 🙂 So you implemented the tag helper but it throws an error when trying to load the page?

Hey, the perfect resource, then! lol Ok so yes it will throw this error: "NullReferenceException: Object reference not set to an instance of an object. SeoToolkit.Umbraco.MetaFields.Core.Common.TagHelpers.MetaFieldsTagHelper.Process(TagHelperContext context, TagHelperOutput output)" For more details, the is in a master template.

Do you have access to the full stacktrace? And do you have any custom code in place that connects to SeoToolkit?

no custom code connecting the SeoToolKit. Here is the fullstack: https://cdn.discordapp.com/attachments/1316048388965400630/1316057076786663537/message.txt?ex=6759a92a&is=675857aa&hm=867f28439620a5d918593e594665fbf9415571ab78cfff247e01fd688fa6af7f&

Hmm, that is super strange as there isn't much that can go wrong in that class (https://github.com/patrickdemooij9/SeoToolkit.Umbraco/blob/8c48a6588a17be02a5132cdc4e4941fe197e1c44/src/SeoToolkit.Umbraco.MetaFields.Core/Common/TagHelpers/MetaFieldsTagHelper.cs#L9) I noticed that you mentioned Umbraco Page Controller. What do you mean with that? Is that using the RenderController from Umbraco?

I am using a composer to create a route path: /about/team/{id}. There is a node at /about/team/bio in the back office. Essentially, I'm using the custom route and an UmbracoPageController/IVirtualPageController to go and find the team member data to populate the bio "shell". For example: /about/team/eric-engle will render a page with my bio. My thinking is that since that is technically a custom route, i might be needing to generate either the taghelpercontext or output in the controller. I have not figured how to do that or if its even possible.

Ah oke, I'll try to see if I can reproduce the issue by using the IVirtualPageController (bit later today, as I am still at work). If I can, then I will make sure to write a fix for it in the package

Sure thing! I am very grateful for any help you're willing to provide.

I've been able to reproduce the issue. I also did some digging and it seems to be an issue within Umbraco itself: https://github.com/umbraco/Umbraco-CMS/issues/12834. I did however find a workaround for it. I just pushed a new version for SeoToolkit (3.6.1) which has this workaround. Could you check if this fixes your issue?

Good morning. I took the update, and I am still getting the same error. I'll try to rework my code to fit the Umbraco fix better to make sure that's not an issue.
