Rollup job unable to start

Elastic Stack Elasticsearch

Sure, so I have a few indices which store historical data. Those indices name start with datalog.gl_* (for eg: datalog.gl_sep20). I then create the rollup job through this:

curl -X PUT "localhost:9200/_rollup/job/compress?pretty" -H 'Content-Type: application/json' -d'
{
  "index_pattern": "datalog.gl_*",
  "rollup_index": "datalog_rollup",
  "cron": "0 */60 * * * ?",
  "page_size": 1000,
  "groups": {
    "date_histogram": {
      "field": "time",
      "fixed_interval": "24h"
    },
    "terms": {
      "fields": [ "domain" ]
    }
  }
}
'

However when I try to start the rollup job through curl -X POST "localhost:9200/_rollup/job/compress/_start?pretty", there is an error saying resource not found task for rollup job not found.
