Luke request for document with a binary field

[Thomas Corthals <th...@klascement.net>]

Hi,


I'm trying to get document details from the Luke request handler and it
fails when my document contains a binary field.


Starting from the techproducts examples, which already contains:

<fieldType name="binary" class="solr.BinaryField"/>

I added this to the schema:

<dynamicField name="*_bin" type="binary"/>


Indexed a simple document which I can get back in a query:

{

    "id": "binary-test",

    "test_bin": "PS9cPQ=="

}


This Luke request fails with code 500 though:

$ curl -s '
http://localhost:8983/solr/techproducts/admin/luke?show=doc&id=binary-test'

Is there something that I can do to avoid this, or is this a bug?
