Hi @Muhammad_Arief_Syahnakri

@Muhammad_Arief_Syahnakri,

Can you confirm which activities you are using inside the workflow?

As per error the error occurs when we try to insert duplicate keys in a variable of type dictionary.

You can’t add more than one item in dictionary with same value.

For example

DictionaryVariable("Name")="Ashok"

DictionaryVariable("Name")="Ashok"

This will give you the error you are getting.

You can check if the key is already exists in dictionary and then add like this.

DictionaryVariable.Keys.Exist("Ashok")

As per your error, your automation trying to create duplicate keys in dictionary, use analyze project to get the errors and try to fix then start debugging so that you can know where it is adding duplicate keys in dictionary.
If you are using any config file check your excel whether you given any duplicate keys.
