An item with the same key has already been added error

Hi All,

I am working on a workflow in which i would need to take values from a datatable and update it in the existing JSON.
I am facing the error “An item with the same key has already been added”. The error is at the assign activity where it is assigning to Dictionary. I understand that Keys in a Dictionary are unique but in my process I would require both the keys. Can you suggest on what modification to be done at the assign activity or at the Invoke to resolve the issue ?

Please find the attached Sample JSON and XAML.

can you tell me which key is repeating

3

The key which is repeating is “gr1”.

4

can you use like gr2 or something ??
if not then you have to store the gr1 values as array in gr1

Thank for the information.
I put the values as 3,6 for the key gr1 and mapped it using index 0 and 1. Please see the screenshots below:

I am getting multiple errors like
1)“Invoke Method: Unexpected character encountered while parsing value: “. Path ‘’, line 0, position 0.”
error

Could you please help me on how to proceed with these errors?

provide the screenshot in which activity error comes

i think $.id is not the right way to give the path calling from json file

If this is not the right way, could you please give a sample XAML or the information to map the JSON Key and Value
