Hello,

i want to write some Values in a Influx Database (V1.8)  
If i send this, it works:

```auto
{
	"_msgid": "add6566.b6dd4a8",
	"payload": {
		"enaNewBatchData": true,
		"reqNewBatchData": false,
		"aknBatchData": false,
		"enaChgCurrentBatch": false
	},
	"topic": "NodeID;ns=3;s=\"Dev\".\"Out\".\"Org\"",
	"measurement": "Dev",
	"statusCode": {
		"value": 0
	},
	"serverTimestamp": "2022-01-27T05:34:17.167Z",
	"sourceTimestamp": "2022-01-27T05:34:17.167Z"
}

```

But when i send this i get the Error "TypeError: Cannot read property 'schema' of undefined" from the influx out Note.

```auto
{
	"_msgid": "add6566.b6dd4a8",
	"payload": {
		"x00": false,
		"x01": false,
		"x02": false,
		"enaNewBatchData": true,
		"reqNewBatchData": false,
		"aknBatchData": false,
		"enaChgCurrentBatch": false,
		"batchDataWrong": false,
		"nextBatchRcpTankNbrWrong": false,
		"enaChgCurrentMilkQty": false,
		"reqNewDataInactiv": false,
		"x13": false,
		"acidRequest": false,
		"lyeRequest": false,
		"coagOk": false,
		"x17": false
	},
	"topic": "NodeID;ns=3;s=\"Dev\".\"Out\".\"Org\"",
	"measurement": "Dev",
	"statusCode": {
		"value": 0
	},
	"serverTimestamp": "2022-01-27T05:34:17.167Z",
	"sourceTimestamp": "2022-01-27T05:34:17.167Z"
}

```

I dont no where i is the porperty "schema"?

Why work the first flow and not the second one?

My Versions:  
Node Red V1.2.9  
node-red-contrib-influxdb 0.6.1  
InfluxDB shell version: 1.8.6

I hope someone can help me

Thanks  
Matthias

I read the Values with the OPCUA Client Note from a PLC (Trigger from a inject Node)

The "\_msgid" come from the "inject Node"
