Hi team,

My date mapping from logstash,

logstash:

date  
{  
match =\> ["logtime" , "yyyy-MM-dd HH:mm:ss"]  
timezone =\> UTC  
}

Field mapping in the template:

"logtime": {"type": "date","format":"yyyy-MM-dd HH:mm:ss"},

When the logstash maps the filed with template am getting below error,

[2019-11-22T15:06:29,634][WARN][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=\>400, :action=\>["index", {:\_id=\>nil, :\_index=\>"lsh-usa\_verizon\_core2a\_8650sdm\_v4-2019.11.22", :\_type=\>"doc", :\_routing=\>nil}, #LogStash::Event:0x6d8370d6], :response=\>{"index"=\>{"\_index"=\>"lsh-usa\_verizon\_core2a\_8650sdm\_v4-2019.11.22", "\_type"=\>"doc", "\_id"=\>"yLXwlG4BIqQPqzL4CoVd", "status"=\>400, "error"=\>{"type"=\>"mapper\_parsing\_exception", "reason"=\>"failed to find type parsed [string] for [logtime]"}}}}

Can some one help where am i missing and how to fix this?

Regards,  
Sathish

I generally have to do target in date filter.

date  
{  
match =\> ["logtime" , "yyyy-MM-dd HH:mm:ss"]  
timezone =\> UTC  
target =\> "logtime"  
}

what is your output when you do without date filter.?  
may be that field is null or something else for that record.
