Every time i open kibana dashboard, i have a shard failure error.
In the elasticsearch log, i can see this error for several fields :
org.elasticsearch.transport.RemoteTransportException: [cFJgxmD][192.168.111.213:9300][indices:data/read/search[phase/query]] Caused by: org.elasticsearch.index.query.QueryShardException: No mapping found for [data.contact2.metadata.TimeInstant.value] in order to sort on
Apparently there is a mapping problem and it happens only with string data.
The dashboard itself is working correctly but there is this error popping all the time.
The visualisation with string data is only to display the last value based on timestamp.
I know there is a config to ignore unmapped value, but as I'm working with elasticsearch 5.3.3 it is ignoring it by default.
So how can I fix it ?
