Hello people.
I have done a custom agent with copilot studio and I want it to connect to a personal API that I have running locally on localhost. I have done some research and in order to do so, I have to download a microsoft gateway, which I have done, and configure it. Done that. Later I have to create a custom connector that connects to the specificied localhost URL through that gateway. As well, I have done that. My problem appears when I try to use this custom connector in my agent through a topic. I have connected and configured my custom connector with my custom agent . Nevertheless, as soon as my topic reaches the part of it that uses the custom connector this error pops up in the window: Lo siento, se ha producido un error. Código de erro: SystemError.

Do not know what is not working. Would love some help.
Thank you
