Any inputs on how to triage and debug further would be helpful

Answer 1

The above error was resolved after completing the following steps.
Step1 - CAS configuration was exported and imported after the addition of the following change. <ignoreInvalidRecords>true</ignoreInvalidRecords>
recordstore-cmd.sh get-configuration -a ART-data -f dataConfig.xml
recordstore-cmd.sh set-configuration -a ART-data -f dataConfig.xml
Step2 - The same change was made in the record store configuration file present under the <CAS_WS>/workspace/state/ART-data
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<recordStoreConfiguration xmlns="http://recordstore.itl.endeca.com/">
<changePropertyNames/>
<idPropertyName>record.id</idPropertyName>
<ignoreInvalidRecords>true</ignoreInvalidRecords><!-- newly added -->
<jdbmSettings/>
</recordStoreConfiguration>
Step3 - The cas_output folder <Endeca_apps>/ART/data/cas_output was replaced with the backup (2 days past) that was available.
After the above steps, indexing was initiated directly from backend (by invoking scripts). Once this indexing was successful, indexing was invoked from the dynamo and the same was successful.
