Error when using "Deserialize JSON Array" activity to read array from .json file

Help

I created a JSON Array file.

It does not matter if the file is of this Structure: [ … { … } …] or this one { … [ … ] …}.

When the process runs there I always get this error message:

Message: The following errors were encountered while processing the workflow tree:
‘StartBackup’: The private implementation of activity ‘1: StartBackup’ has the following validation error: Compiler error(s) encountered processing expression “configTEST”.
Der Wert vom Typ “Newtonsoft.Json.Linq.JArray” kann nicht in “Newtonsoft.Json.Linq.JArray” konvertiert werden. Der Typenkonflikt könnte auf das Mischen eines Dateiverweises auf “C:\Users\decurmos.nuget\packages\newtonsoft.json\12.0.3-beta1\lib\net45\Newtonsoft.Json.dll” in Projekt “vbhost” mit einem Dateiverweis auf “C:\Users\decurmos\AppData\Local\UiPath\app-19.8.0\Newtonsoft.Json.dll” in Projekt “vbhost” zurückzuführen sein. Wenn die beiden Assemblys identisch sind, ersetzen Sie die beiden Verweise durch Verweise vom gleichen Speicherort.

I hope the workflow itself is not valid @kwoxer

Please check there are some error warnings inside the workflow which you need to clear first to execute the workflow :slight_smile:

Actually I cleaned up the used Packages and deleted some like JSON.net and Nancy.Serialization.JsonNet. Now I can run the activity again. Issue solved.

Maybe someone can additionally tell me why there is an error when using multiple Json packages? That’s sounds like a strange behaviour to me.
