**I solve that using this methodology.**

1. Your Node Input must be an `IDictionary`.

2. Then, inside in your Node logic you need to convert the IDictionary to a strong typed Dictionary.

This allows you to consume your input data as you wish.

See images below showing how I implement that.

**Node Method**

**Generic extension method to convert IDictionary to the strong typed Dictionary**
