Hello Folks !

I have encoutered an exception when indexing data field : "org.elasticsearch.index.mapper.MapperParsingException: failed to parse date field [], tried both date format [dd/MM/yyyy], and timestamp number with locale []"

I tried to add "null" instead of "" but it doesn't resolve the problem ! The issue is that data input for field date can be written in different ways, so It's impossible to add "format" : "MM-dd-YYYY" to the mapping.

I check if there is an old template that exists when indexing but nothing found 😕

PS : I set up a cluster of 3 nodes

Any idea?
