NPE in ObjectMapper.parse

Elastic Stack Elasticsearch
1

Hi there,

I have a river plugged to a couchdb that gets a few thousands documents updated.

I get the following NPE:

[DEBUG][action.bulk ] [Evilhawk???] [germany][0]: Failed to execute bulk item (index) [index {[germany][db1][c20147700], source[{"_rev":"1-e4e4f2b0aa87c0af9fbb6e1bf3f8b894","parents":{},"_id":"c20147700","children":{"None":["c20171489"]},"properties":{"feature_code":1111,"attributes":{"#D":"COUNTRY","#A":5,"#C":2,"#L":"GER","22":"EUR","IC":"DEU","#M":"M","12":0}},"type":"Feature"}]}]

Is it because the document to index contains "parents":{} ?

Thanks for your help,

The NPE is produced when using a wrong mapping.
The "IC" field is a string, and not an object.
I had in the mapping:
"IC": { "properties": { "text": {"type": "string", "index": "not_analyzed"} } }
It should have been:
"IC": { "type": "string", "index": "not_analyzed"} }
