Kibana - creation index


I created an Indexname from the “Configuration Elasticsearch” gateway to use the information to generate and customize graphics on Kibana.
The problem is that I get the creationDate field in the Long type instead of the Date type, which does not work on the Kibana side.

=> file generate by the gateway
“creationDate”: {
“type”: “date”,
“format”: “strict_date_optional_time||epoch_millis”

= > file generate after creating the index
“creationDate”: {
“type”: “long”

Can anyone provide information about this?

Hi Marouane,
API Gateway by default generates the creationDate field as long value. The reason being, with long values, the data can be converted into any date format including the timezone specifics and this conversion is out of the box supported in all versions of Kibana. API Gateway dashboard by default has this settings added. Incase if you are using an external Kibana, please mention how the creationDate field should be treated by the Kibana server.
