Hello @Kirubakaran_Kannan,
I hope you have installed Workflow Manager Activities under dependencies :
When you drag and drop “Clear Dictionary” into the workflow, it will ask the Key, Value type. Ensure you set this right (based on your original dictionary i’m sure if its String, String or String, Object. You can check this in the Variables Panel)
Now pass the dictionary to the said activity. It should work as expected.
Hope this helps. Kudos
Regards,
Nithin
