Getting error as "The given key was not present in the dictionary uipath"

I am very new to UIpath, so please forgive me for any errors.
So, I am trying to replicate the process I automated using Excel VBA+Selenium to UIpath. In that, I have a step to get a set of details from a table stored in a database using API. And when I Run the the HTTP request it shows me an error “The given key was not present in the dictionary uipath”
The API has a Key and value linked to it.
As very new to this I not sure what does the error message means, also I tried to google it and unable to find anything.
Below are the screen shots of my Sequence and error messages.

Are you passing the key as a argument? If so, check you defined the argument correctly

Hope this may helps you


Sorry I might sound silly. But could you please tell me how to do that or point me to a place to learn that.
Just to let you in the HTTP wizard when I did a preview it did work.
