workflow to update an item

[Chiefmas 40]

Ok, hopefully this will be my last post and I'll be able to get the last bits from here...

Initially I was trying to submit to the IitemUpdateService using a post to this endpoint(the ID is correct for my test item): /Items/1348003
Using this as the body (double quoting is escaping in code, they are sent in the post as single quotes):

{
    ""TagItems"": [
        {
            ""Name"": ""add1""
        },
        {
            ""Name"": ""add2""
        }
    ]
}

That gives me a 400. I had hoped I could just submit the fields to change to the ItemUpdateService, but I keep getting 400s back, so now I suspect that I actually need to submit the entire BaseItemDto object back? When I check the server logs, the error in the stack trace is:

	System.ArgumentNullException: System.ArgumentNullException: Value cannot be null. (Parameter 'source')
	   at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
	   at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)
	   at Emby.Api.ItemUpdateService.UpdateItem(BaseItemDto request, BaseItem item)
	   at Emby.Api.ItemUpdateService.Post(UpdateItem request)
	   at Emby.Server.Implementations.Services.ServiceController.<>c__DisplayClass8_0.<VoidActionDelegate>b__0(Object service, Object request)
	   at Emby.Server.Implementations.Services.ServiceController.Execute(HttpListenerHost appHost, Object requestDto, IRequest req, Type serviceType)
	   at Emby.Server.Implementations.Services.ServiceHandler.ProcessRequestAsync(HttpListenerHost httpHost, IServerApplicationHost appHost, IRequest httpReq, IResponse httpRes, IStreamHelper streamHelper, RestPath restPath, String responseContentType, CancellationToken cancellationToken)
	   at Emby.Server.Implementations.HttpServer.HttpListenerHost.RequestHandler(IRequest httpReq, ReadOnlyMemory`1 urlString, ReadOnlyMemory`1 localPath, CancellationToken cancellationToken)
	Source: System.Linq
	TargetSite: Void ThrowArgumentNullException(System.Linq.ExceptionArgument)

So, I'm not sure what I'm doing wrong, otherwise. If I do need the entire BaseItemDto object, is there an easy way to get that back, so I can just edit it and submit it back? The Item service doesn't appear to return a BaseItemDto, rather it seems to return a subset of that. Docs seem to be telling me I should be getting an entire BaseItemDto, but I don't think that's what's happening when I make a call to /Items?ParentID=18060&AnyProviderIdEquals=imdb.tt14961624 I get a single item back, but as I said, it doesn't seem to be a complete BaseItemDto object.

Thanks for all the help, I really appreciate it!

Ah, ok I found a bug in my code, and I figured out that I am able to add them using the tag service, so I might be set, thanks...

For anyone reading this, I switched to the TagService, i.e. made my endpoint /Items/1348003/Tags/Add and I am able to add tags that way.

Given that I had a bug, I'm going to go back to testing using the ItemUpdateService and see if I can get that working, but I have at least something that works. I'll have to do some more testing to see if the tag service will work better...I need to see what happens when I submit duplicates. I'm kind of hoping that the ItemUpdateService just replaces all the existing tags with what I submit, as that may present some advantages but regardless, I have a way that at least gets the basic thing going.

Thanks!
