Swift Alamofire.upload: Type of expression is ambiguous without more context

Question

I'm getting the Type of expression is ambiguous without more context error in my code and I'm not sure why. I used the same method before and I never got this error before.

I saw similar posts here regarding this error, but none of the solutions fixed it for me. For example I tried changing to to with and it didn't do anything. Any help would be appreciated.

I'm using:

1. Alamofire version 5.5.0

2. Xcode version 14.0

3. Swift version 5.0`

        Alamofire.upload(
        multipartFormData: { multipartFormData in
            if firstButtonFileType == "image"
            {
                let imgData = firstButtonImage.jpegData(compressionQuality: 0.5)
                multipartFormData.append(imgData!, withName: "homework", fileName: "homework.png", mimeType: "image/png")
            }
   
            if firstButtonFileType == "document"
            {
                multipartFormData.append(linkOfFirstFile!, withName: "homework", fileName: "homework." + firstFileExtension, mimeType: "application/pdf")
            }
   
            if secondButtonFileType == "image"
            {
                let imgData2 = secondButtonImage.jpegData(compressionQuality: 0.5)
                multipartFormData.append(imgData2!, withName: "homework1", fileName: "homework1.png", mimeType: "image/png")
            }
   
            if secondButtonFileType == "document"
            {
                multipartFormData.append(linkOfSecondFile!, withName: "homework1", fileName: "homework1." + secondFileExtension, mimeType: "application/pdf")
            }
   
            if thirdButtonFileType == "image"
            {
                let imgData3 = thirdButtonImage.jpegData(compressionQuality: 0.5)
                multipartFormData.append(imgData3!, withName: "homework2", fileName: "homework2.png", mimeType: "image/png")
            }

            }
   
            multipartFormData.append(defaults.string(forKey: "user_idx")!.data(using: String.Encoding.utf8)!, withName: "student_idx")

                    print(response)
                    if response.result.value != nil {
                    } else {
                        // internet connection error
                    }
                }
            case .failure(let error):
                print(error)
            }
        }
