Trying to debug a solr error

[Phil Rosen <pr...@optaros.com>]

I am getting the following error from Solr when my application is deployed
on Tomcat on Redhat, but everything works well on Tomcat on XP. Can anyone
point me in a direction of the cause?

 

The schemas for the two deployments are identical, but the error persists!

 

Thanks in advance,

Phill

FYI: leting us know what action you were performing when an error is
triggered is helpful.

based on my reading of the stack trace, you are "updating" a document and
the problem is that the document you are sending to the Solr server does
not have a uniqueKey field in it.

there is some error checking in UpdateHandler.getIndexedId(Document) that
is suppose to check for this and throw a more useful error message
("Document is missing uniqueKey field " + idField.getName()) ... but based
on your stack trace it looks like there's an NPE before that check
(doc.getField probably returning null)

Can you double check that you have a value for your uniqueKey field in the
document you are trying to add ... if that really is the cause of hte
problem, then it would be great it you could file a bug to improve the
error handling/reporting.
