Error [... is not a literal node]: Modyfing artifact properties when artifact has "link to"
Hello Community, I have following Issue:
Problem description
I am able to modify the the attributes of an artifact without any issues as long as the attribute hasn't any link to a requirement. When the attribute has a link to an requirement following error occurs:
>https://jazz.XXX.com/rm/resources/TX_CVfu-lDmEeuWbbdnw2HZow is not a literal node</err:detailedMessage>
I linked the Evidence --> a requirement.
Used Programming language: C# VS
API: OSLC-Core-Version=2.0
Code
//Request: Get Artifact
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(milestones.EvidenceResource);
request = createRequest(request, context); IWebProxy proxy = WebRequest.DefaultWebProxy; // Uri proxyUri = proxy.GetProxy(request.RequestUri); bool isBypassed = proxy.IsBypassed(request.RequestUri); if (!isBypassed) proxy.Credentials = context.ProxyCredential; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); var reader = new StreamReader(response.GetResponseStream()); var etag = response.Headers.Get("ETag"); var Replace = reader.ReadToEnd();
**Response I get [WHEN Artefact has a link to a requirement:]
[Received Body --> and I send the same body PUT without any modification]

Update and answer to this question:
The problem could be narrowed down to when an artifact is linked with a custom link (without predefined URI) to a requirement. (Standard Links defined by DOORS worked fine)
Solution: Each custom link needs to have a URI (Link types setting) defined when updates via OSLC are done.
