Hi,  
I am trying to read iot data from azure IoT-Hub built-in endpont consumer group - created input plugin, and output plugin to write data on json file. When I run telegraf, it’s creating empty json file  
Does anybody can help me here. Using telegraf version 1.37.1  
**telegraf.conf**

`[[inputs.eventhub_consumer]]`  
`data_format = “json_v2”`  
`[[input.eventhub_consumer.json_v2]]`  
`timestamp_path = “Payload.timeseriesData.#.timestamp”`  
`timestamp_format = “2006-01-02T15:04:05.0000000Z”`  
`[[input.eventhub_consumer.json_v2.tag]]`  
`path = “Payload.iothub-connection-device-id”`  
`rename = “device_id”`  
`[[input.eventhub_consumer.json_v2.tag]]`  
`path = “plantCode”`  
`rename = “plant_code”`  
`[[input.eventhub_consumer.json_v2.field]]`  
`path = “timeSeriesData.#.value”`  
`type = “float”`  
`[[outputs.file]]`  
`files = “C:\telegraf\iot_data.json”`  
`data_format = “json”`

**Sample data** at iot built-in endpoint:

```auto
”Paylod”: {
”iothub-connection-device-id”: “BE01-01-edge-dev”,
”iothub-enqueuedtime”: “2026-02-23:T12:20:00.5000000Z”,
”plantCode”: “BE01”
”timeSeriesData”: [
{
”value”: 200.5,
”tagCode”: “11aa22bb-a1b1-11aa-aa11bb22”
},
{
”value”: 100.5.
”tagCode”: “11cc22dd-c1d1-11cc-cc11dd22”
}
]
}

```

When run in - - test mode: Got an error

```auto
E! [agent] Starting input inputs.eventhub_consumer: creating receiver for partition ‘0’: *Error{Condition: amqp:link:stolen, Description : At least one reciever for the endpoint is created with epoch ‘0’, and so non-epoch receiver not allowed”

```

I tried with changing epoch = 10 and epoch = 1, still telegraf is not creating data in output json file
