I am getting mapper parsing exception while indexing dates at ES :

{  
"type": "mapper\_parsing\_exception",  
"reason": "failed to parse [completionTime]",  
"caused\_by": {  
"type": "illegal\_argument\_exception",  
"reason": "Invalid format: "2019-05-07T02:46:16Z" is malformed at "Z""  
}

Sometimes this issue reproduces and sometimes not.

Actually, I am using OffsetDateTime Format as :-  
private OffsetDateTime completionTime;

before indexing, I am converting time to string using toString().

Can someone help me to resolve this issue ?

Hey @rvyas  
Can you please share your mapping for this index?  
Specifically for the completiontime field
