Exception : Error reading JObject from JsonReader. Current JsonReader item is not an object

George Tsamis 11 months ago in Devices / Http • updated 10 months ago • 4

I have an http response like:

[{"1":"WiBee - Reset Energy Counters","v":true},{"1":"WiBee - Phase 1 Voltage","v":232.48},{"1":"WiBee - Phase 2 Voltage","v":225.12},{"1":"WiBee - Phase 3 Voltage","v":228.64}]

I have used the token name [1].v to get the Phase 1 Voltage but i always get an error 

Debug : 20/1/20 6:37:20 μμ : Devices\GetEnergyMeterData\FetchDataFromLM : Exception : Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 1, position 1. ...

Any help?

Hi,

In fact, if I load the response on a JSONPath Expression Tester (e.g. https://jsonpath.curiousconcept.com/), I get the correct value with the [1].v token

Do you have the correct parser type set?

Can you test with .[1].v ?

Hi,

I know the path is correct but i always get the same error and no value.

I laso tried .[1].v [2].v .[2].v and datatype string with the same token names without any luck

check attached screenshots if i am missing something

Hi,

Can you tell us which configurator version you're using?

On a previous version, it seems that http devices with authentication we're having some problems. Can you check that and tell us?

Best regards

Sorry for late reply.

Configurator version is 4.6.26
