Custom Connector Action does not allow me to provide Inputs

Hi, so I was playing around with a Co-pilot agent where I wanted to call one of our Custom Connectors integrated within our system to fetch and use the data. However, when I include my action into a Topic, when I select the inputs which are required for my Custom Connector, I get met with the following error messages:
 
 
Could it be the "'" in the input that is throwing it off? It seems quite self explanatory however I cannot progress with my conversation due to these. Even if I save past the error message. I have also tried removing the "'" from the binding in the code editor but then these inputs disappear after a save.

Within the code editor, my inputs look like:
input:
        binding:
          "'Access-Token'": =Topic.token
          "'Content-Type'": application/json
Could anybody possibly point me in the right direction?
 
Thanks in advance!

    I confirm, you are not supposed to have the quotes , the problem come from the configuration of you connector wich use too much quote , a normal custom action from my tenant look like this way

     
    code behind
     
     
    So you could correct in your connector, configure connector to use property automaticaly without custom type, or ask you developper

    When you use the custom connector out of Copilot scope, does it need two parameters ? 
    Have you tried send http request to see if you can get response ?
