Hi

If i have some json sent as varaible to the open source engine and i want to take some field within the json and to use it in some tasks expression (condition,call activity etc,) do you have something which can be used in the expression like ${JSON(json).filed(name)} or i need to use a javascript/delegate for parsing it

Hey @netanelk,

Are you sending a JSON string or a JSON object? How are you sending the variable?

If you send it as a json variable then you can just do `${json.name}` in your expressions.

Cheers,
