I updated some indices mapping to simply add a keyword field to a text property and reloaded Kibana's index patterns. I was told I should run this command at the end:
POST 11ad.pi.prod.test-case-18/_update_by_query?conflicts=proceed
after doing it I get an error:
{
"statusCode": 504,
"error": "Gateway Time-out",
"message": "Client request timeout"
}
does it mean the timeout is too short?
