TypeError: status.indices[index] is undefined

I've got a cluster with some unassigned shards, I'm getting this error:

TypeError: status.indices[index] is undefined

It's crashing on this line:

if(node === "Unassigned" || !status.indices[index].shards[shard]) {

status.indices is missing logstash-2014.10.10 (value for shard). I'm afraid I can't give reproduction instructions, it occurred during a 1.1 -> 1.2.4 migration whilst some shards were still unassigned.

As a result, it's not possible to see the status of my cluster on the main page of elasticsearch-head.

FWIW, I was able to work around the issue by using a debugger to see which indices were causing problems, then using the elasticsearch API to close those indices. The page then rendered as expected.

I had the same issue - it appears to happen after a cluster crash when the health is red. I added an extra statement to the line and it works fine:

if(node === "Unassigned" || !status.indices[index] || !status.indices[index].shards[shard]) {
