On Solr I get this error:

Parallel to this, I got some log messages on Solr before attempting to reindex the user (sorry for the garbadged text:

These errors are a LOT longer than what we see here.  It appears that you are showing us what you can see in the logging tab of the admin UI ... you will see far more detail if you find the solr.log file and get information from there.  Full detail can be seen on a single log entry in the admin UI by clicking on the little "i" icon, but it will close again *VERY* quickly, so that's not a very reliable option.

The full detail is usually required for deciphering log messages.

As for the source of the problem ... these look like the kind of errors that can be encountered if you complete some indexing with one schema, then change the schema without deleting the existing index, restart/reload, and try to index more data.  Most changes to the schema will require full reindexing, and some changes require actually deleting the index directory entirely and allowing it to be rebuilt.  In some rare cases, upgrading Solr *might* result in a change to the schema that requires deleting the index even though the schema config file itself is the same.  I do not know if your setup is one that would be affected in this way.

Your question is more appropriate for the solr-user mailing list at Apache than this list ... but I did not expect you to know that in advance.  I can try to help you.
