NullPointerException in Graph Traversal nodes streaming expression
Solr version 8.4. I’m getting an unexplanetory NullPointerException when executing a simple 2 level nodes stream, do you have any idea what may cause this?
I tried setting /stream?partialResults=true&shards.tolerant=true and shards.tolerant=true in nodes expressions, with no luck. I also tried reading source of GatherNodesStream in branch 8_4, but couldn’t understand it. Here is a beautiful stack trace:

Re: NullPointerException in Graph Traversal nodes streaming expression
Posted by Joel Bernstein <jo...@gmail.com>.
How are you constructing the Stream with classes or using a Streaming
Expression?
In either case can you post either the code or expression?
Are there more errors in the logs? The place where this NPE is occurring is
that an underlying stream is null, which leads me to believe there would be
some exceptions before this, possibly on a different server if this has
multiple servers involved.

Re: NullPointerException in Graph Traversal nodes streaming expression
Posted by Mike Drob <md...@mdrob.com>.
Can you provide a sample expression that would be able to reproduce this?
Are you able to try a newer version by chance - I know we've fixed a few
NPEs recently, maybe https://issues.apache.org/jira/browse/SOLR-14700
