Automation: show error if required property not in query

[silvester-pari]

Currently, when calling an automation via query params, there is no error message if a required property is missing. Later it fails randomly at some point if that property is used in automation steps, giving the user an error message which is hard to understand. For example:

    inputSchema: {
      type: "object",
      properties: {
        file: {
          type: "string",
          minLength: 1,
        },
        type: {
          type: "string"
        }
      },
      required: ["file", "type"],
    },

--> if the automation call url is missing query param of "file" or "type", then the automation should immediately abort/not start and show the user that the parameter is missing.
