Process Workflow: Given key is not present in the dictionary in UiPath

Question

I am doing UiPath level-3 Assignment 1. I have made all the workflows using Ui Studio and I am stuck in the process workflow. While I run the WFs, it says

I checked all the values and arguments and they seem correct too.

Also when I run the Process WF separately, it gets stuck for each loop and says

Process WF: the Given the dictionary is not present.

Could someone help to resolve these issues? Thanks in advance.

object reference not set to an instance of an object.

Answer 1

I would ask you are passing null value/trying to get value from the dictionary using the key which doesn't exist. 

Or you can check the spaces in the data.
