OPCFoundation
endpoint infomodel/types/{identifier} returns 404 when called with type identifier
I try to read the type information of a certain type via cloud library. When calling the infomodel/types/{identifier} with nsu=http://opcfoundation.org/UA/Machinery/;i=1002 or http://opcfoundation.org/UA/Machinery/;MachineryItemState_StateMachineType it returns 404 (not found) instead of the type description as JSON.
The API seems currently to only work with model identifiers (like 2797226801 for Machinery Basic Building Blocks) and then list the types.
I've investigating this today. This is "by design". The infomodel/types/{identifier} only lists the types, or returns a 404 when no types are defined in the nodeset (I've made the error returned a little better so it doesn't look like a bug). Do you need the references, per node, as well?
This is now fixed with https://github.com/OPCFoundation/UA-CloudLibrary/commit/92808eb9b0b1ed3db137ed8864693cd143bc1cb9.
I used infomodel/types/{identifier} because the original infomodel/type API doesn't exist anymore. And currently don't see, how I can query the type-definition of a concrete type.
Just tested, still don't work.
What do you expect to see that you don’t see?
iPhone. iTypos. iApologize.

I expect that I can query the details of a certain type like MachineryItemState_StateMachineType in the namespace http://opcfoundation.org/UA/Machinery/ to get the JSON representation of that type...
Or is cloud library now only for upload/download nodeset files?
No, this should work. Problem reproed and confirmed and working on a fix...
It is fixed now (with check-in https://github.com/OPCFoundation/UA-CloudLibrary/commit/6745e7703520412cd904f6606a38d1fc13389728)
Is it already deployed? I tested via https://uacloudlibrary.opcfoundation.org/swagger/index.html and still only get 404.
Yes, it is. Check browser cache?
I now get:

Oh I see, when I now use the infomodel/types/{identifier} API with the model identifier 2797226801 the JSON that describes the types will be returned instead of just the names but I can't ask for a single type like http://opcfoundation.org/UA/Machinery/;MachineryItemState_StateMachineType
That's correct. We decided to return all types at once, to align with the behavior of infomdel/instances/{identifier}. A little bit more parsing on the client side required, granted.
