Hello!

I am unable to perform preprocessing with JSONPath.
My preprocessing JSONPath with a comparison operation - $.data.result[0].metric.container_label_com_docker_swarm_task_name =~ ".*"
I want get 2 "container_label_com_docker_swarm_task_name" which in this case is efk_fluentd.1 and nexus_nexus.1 for LLD

My Json data:

_{ 
   "status":"success",
   "data":{ 
      "resultType":"vector",
      "result":[ 
         { 
            "metric":{ 
               "__name__":"fluentd",
               "instance":"10.0.3.18:9308",
               "job":"fluentd_exporter",
               "container_label_com_docker_swarm_task_name":"efk_fluentd.1"
            },
            "metric":{ 
               "__name__":"nexus",
               "instance":"10.0.3.18:9308",
               "job":"nexus_exporter",
               "container_label_com_docker_swarm_task_name":"nexus_nexus.1"
            },
            "value":[ 
               1580296145.761,
               "3"
            ]
         }
      ]
   }
}_

I get an error:

Preprocessing failed for: {"status":"success","data":{"resultType":"vector","result":[{"metric":{"name_":"container_memo...
1. Failed: cannot extract value from json by path "$.data.result[0].metric.container_label_com_docker_swarm_task_name =~ "."": unsupported construct in jsonpath starting with: " =~ ".""_
For this setting, I followed the official Zabbix documentation.
