Prometheus file-based service discovery failed

[ckanner]

I use prometheus as a metrics receiver, and use file-based service discovery. But it scrape failed. The error message is
2020-08-31T17:06:34.178+0800 INFO scrape/scrape.go:972 {"component_kind": "receiver", "component_type": "prometheus", "component_name": "prometheus", "level": "debug", "scrape_pool": "dummy", "target": "http://192.168.100.162:8079/metrics", "msg": "Append failed", "err": "unable to find a target group with job=logic.cmdb_service"}

The reason may be a job label added to the json file.

The collector config file is

receivers:
  prometheus:
    config:
      scrape_configs:
        - job_name: "dummy"
          scrape_interval: 10s
          file_sd_configs:
            - refresh_interval: 1m
              files:
                - "/data/conf/targets.json"
          metric_relabel_configs:
            - source_labels: [__name__]
              regex: "(service_request_duration_seconds_total|service_requests_total)"
              action: keep

      processors:
        - batch
        - queued_retry
      exporters:
        - logging

The targets.json is

[
  {
    "labels": {
      "job": "logic.cmdb_service"
    },
    "targets": [
      "192.168.100.152:8079"
    ]
  }
]

I want to use the job key to rewrite the scrape job name.

How can I resolve it?
