GPT Action executes without connecting to my backend and returns a `{}` response

The solution was that I had incorrectly specified my schema, but this wasn’t being picked up anywhere.

My schema was (snipped to the relevant part):

"parameters": [
  {
    "schema": {
      "description": "Parameter description"
    },
    "required": false,
    "name": "foo",
    "in": "query"
  },
],

When, instead, I should have included a type in the parameter’s schema, like:

"schema": {
  "type": "string", 
  "description": "Parameter description"
},

Including this caused it to connect correctly.
