@jamieb22 this issue should be fixed. Could you try the latest version?

[jamieb22]

I tried on the latest version 2.2.9 and it doesn't work.

This happens on v_statistic.subtype and v_blob.mgn

[andrii0lomakin]

Hi @jamieb22 by latest I meant 2.2.10 which was in snapshot stage when I wrote it.
If you check OIndexAbstract#getVersion
you will see following code:

    final ODocument document = conf.getDocument();
    if (document == null)
      return -1;
    return document.field(OIndexInternal.INDEX_VERSION);

So NPE on a document should not happen. Could you try on 2.2.10 ?
