[CS 16.2.x REST API] Creating a node with Categories in one call? 2

Paul Gullas

Hi,

I'm using C# and Postman with CS 16.2.8 REST API.

I can upload a document with the REST API. I can use the PUT api/v2/nodes/{id}/categories/{category_id}/ endpoint to add Category values to a node that already has the Category applied to it.

But, when I try to upload a document (or create a folder) and include Category info in a single call, I get 500'd.

This is from the implementation notes:

V2 example to create a node with this category
    Syntax
    - POST api/v2/nodes
    - body = {"name":"myName","parent_id":2000,"type":0,"roles":{"categories":{"[category_id]_[attribute_id]":"Value goes here"}}}

    Example:
    - POST api/v2/nodes
    - body = {"name":"myName","parent_id":2000,"type":0,"roles":{"categories":{"15384_2":"Value goes here"}}}
    
Basically, everything except for "roles" works. If I use Postman, I add a new key called "roles". The value is {"categories":{"5072_2":"Staging"}}. And then when I send the request, I get back a 500 error with this body:
{
    "error": "An illegal attempt was made to upload a document"
}

I'm attaching a screenshot of my Postman form.

Does anyone know what the proper request should look like?

Here is my C# code for creating a folder. The part in the (if (myCategory != null)) block doesn't work for the same reason:

        public async Task<long> CreateFolderAndReturnId(long parentId, string folderName, string ticket, CategoryMetadataTest myCategory = null) {
            Log.Information("Creating folder called {folderName} inside folder {parentId}", folderName, parentId);

            var client = ClientFactory.CreateClient();
            int folderType = 0;
            long folderId = -1;

            MultipartFormDataContent mfdcRequest = new MultipartFormDataContent();
            
            StringContent type = new StringContent(folderType.ToString());
            StringContent parent = new StringContent(parentId.ToString());
            StringContent name = new StringContent(folderName); //name in content server

            mfdcRequest.Headers.Add("OTCSTICKET", ticket);

            mfdcRequest.Add(type, "type");
            mfdcRequest.Add(parent, "parent_id");
            mfdcRequest.Add(name, "name");

            if (myCategory != null) {
                string testCategoryInfo = @{"categories"":{""5072_2"":""Staging""}}";
                StringContent scTest = new StringContent(testCategoryInfo);
                mfdcRequest.Add(scTest, "roles");
            }

            try {
                var response = await client.PostAsync(GetNodeUri(), mfdcRequest);
                response.EnsureSuccessStatusCode();
                var stringResult = await response.Content.ReadAsStringAsync();
                CreateFolderResponse createFolderResponse = JsonConvert.DeserializeObject<CreateFolderResponse>(stringResult);
                Log.Information("Received {stringResult}", stringResult);
                folderId = createFolderResponse.results.data.properties.id;
                Log.Information("Successfully created folder in {parentId}", parentId);
                Log.Information("FolderId = {folderId}", folderId);
            }
            catch (Exception e) {
                Log.Error(e, "Error creating folder in {parentId}", parentId);
            }
            return folderId;
        }

The implementation notes are correct but your example in POSTMAN isn't using the body parameter.

When I use my REST client I POST api/v2/nodes and have only two form fields

key = body
value = {"name": "Best file","type": 144,"parent_id": 2000,"roles": {"categories": {"2530_2": "MY VALUE"}}}

key = file
vlue = file to be uploaded of type file, not a string path.
