Rollup index time issue

Hello,

I am trying to create dashboards with “rollup” index but no luck due to time field.
I am able to add time field in data source settings, but in dashboard section it showing warning “Could not find a rollup job that can answer this query because [missing field @timestamp.date_histogram]

I have tried with Grafana versions 8.4.2 & 9.0.6, but same error.

Data Source settings:

Dashboard:

Rollup index mappings:

          }
        }
      }
    }
  }
}

It would be a great help if somebody suggest me with the solution.

Thanks in advance
