Thread 1: signal SIGABRT - Decoding JSON Array of Objects and into Struct Instance

Hello :)

I am trying to decode a JSON stock market API then store the returned information in an instance of a struct but am getting Thread 1: signal SIGABRT on the struct instance line of code.

The JSON data is in an array of objects that would like this:

{
    "pagination": {
     ... //Not interested in storing this info
    },
    "data": [
        {
            "open": 129.8,
            "high": 133.04,
    },
    [...] //would be data for other symbols
  ]
}

Struct Declaration:

struct SingleData: Decodable {
    let open: Double
    let high: Double
  }

struct ScrapeStruct: Decodable {
  let data: [SingleData]
}

Struct Instance:

var QQQ = try ScrapeStruct(from: Decoder.self as! Decoder) //Thread 1: signal SIGABRT error

Target Output says "Could not cast value of type 'Swift.Decoder.Protocol' (0x1db05bc88) to 'Swift.Decoder'". I know that this is in reference to the .self but I tried other things like Decoder() and even SingleData() or ScrapeStruct(). But just got compiler errors about it not being initialized and that it's missing from: Decoder respectively. And with the struct containing an array and me having issues working with individual values like QQQ.high because ScrapeStruct has no member high I just have no idea what is supposed to be here.

I don't know if this part of the code is helpful but I will include it anyways just in case.

Function:

func Scraper() async throws -> ScrapeStruct {
   guard let url = URL(string: "MarketStack API")
  else {
     throw Error.invalidServerResponse
    }
  var request = URLRequest(url: url)
  request.addValue("My Access Code", forHTTPHeaderField: "access_key")
  request.addValue("QQQ", forHTTPHeaderField: "symbols")
  let (data, _) = try await URLSession.shared.data(for: request)
  let scrapeStruct = try JSONDecoder().decode(ScrapeStruct.self, from: data)
  return scrapeStruct
  }

Call Function:

Task {
    let fetchedInfo = try? await Scraper()
     
    DispatchQueue.main.async {
      if let fetched = fetchedInfo {
        QQQ = fetched
      }
    }
  }

Any help at all would be greatly appreciated. Thanks!
