What could be causing a 400 bad request on item retrieval in DNG?
![]() DNG version: 6.0.5
When we create an item in DNG via our API integration, when we try to retrieve the same item, we get a 400 bad request without much more detail.
Some more pieces that we tracked down from our logs were around a lot of warnings about an invalid cookie with the expiry being in 1994 for the LtpaToken2 cookie (unsure if those are related).
We also took a look at the DNG logs that GM sent us and saw "<unauthenticated>" as a part of it, so it seems that maybe this is related to the LtpaToken2.
Also, these entries seemed to be connected:
java.lang.NullPointerException
at com.hp.hpl.jena.rdf.model.impl
<wbr>
.ModelCom.add(ModelCom.java:
<wbr>
1089)
at com.hp.hpl.jena.rdf.model.impl
<wbr>
.ResourceImpl.addProperty(Reso
<wbr>
urceImpl.java:280)
Any ideas/pointers as to what to look at to figure this out?

The LtpaToken2 expiry warnings are definitely unrelated. The NullPointerException appears to be caused by some corruption in the DNG index, but whether it is related is a different story. I expect a bit more information returned in the HTTP response body or the rm.log file for the HTTP 400 error.
I attached what we found in the DNG logs in more length, as far as the API response, we are not getting much.
