Hello

I love the look of this application and want to start using it for some projects at work, but I've hit an issue when making any sort of query against the endpoint. *Not* passing in the query param gives me a UI error, so I know the forwarding is working OK. The output from the application at the time of the panic is below and includes the request:

I'm very open to the possibility that this is something I am doing incorrectly, but as far as I can tell I have followed the docs

Many thanks,
