"Resource path does not exist" Error

I am developing an app using WhisperKit and SwiftUI for iPhone.

I keep getting this error while using the transcribe method: Resource path does not exist file:///Users/{myuser}/Library/Developer/CoreSimulator/Devices/BF68DAF2-55B5-43A2-B0B1-03969ACAB6A8/data/Containers/Data/Application/21A29C2D-BFB3-41E9-9821-3D464901F1A5/Documents/audio.mp3

I'm sure the file exists since I can see it in the folder. The file has been copied and moved to the Documents folder after being picked with fileImporter, like so:

func moveFileToAppDirectory(sourceURL: URL) -> URL? {
        let fileManager = FileManager.default

        // get permissions
        if sourceURL.startAccessingSecurityScopedResource() {
            defer { sourceURL.stopAccessingSecurityScopedResource() }

            // force iCloud download
            if fileManager.isUbiquitousItem(at: sourceURL) {
                do {
                    try fileManager.startDownloadingUbiquitousItem(at: sourceURL)
                    print("File downloaded from iCloud.")
                } catch {
                    print("Error downloading from iCloud: \(error.localizedDescription)")
                    return nil
                }
            }

            let fileExtension = sourceURL.pathExtension

            // get document path
            if let documentsDirectory = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first {
                // create new path
                let destinationURL = documentsDirectory.appendingPathComponent("audio.\(fileExtension)")

                do {
                    // If it already exists, remove it
                    if fileManager.fileExists(atPath: destinationURL.path) {
                        try fileManager.removeItem(at: destinationURL)
                        print("File removed: \(destinationURL)")
                    }
                    // copy in the document folder
                    try fileManager.copyItem(at: sourceURL, to: destinationURL)
                    print("File copied in \(destinationURL)")
                    return destinationURL
                } catch {
                    print("Error: \(error.localizedDescription)")
                    return nil
                }
            }
        } else {
            print("No permission given to access the file")
        }
        return nil
    }

I handle the file pick in this way:

func handleFileMediaResponse(_ result: Result<URL, any Error>) async {
        selectedAudio = nil
            switch result {
                case .success(let success):
                    // move file to private documents folder
                    if let newFileURL = moveFileToAppDirectory(sourceURL: success) {
                        selectedAudio = newFileURL
                        // download whisper model
                        let folder = try? await WhisperKit.download(variant: "base", progressCallback: { progress in
                            downloadProgressValue = Float(progress.fractionCompleted)
                            print(downloadProgressValue)
                        })
                        let pipe = try? await WhisperKit(modelFolder: folder?.absoluteString, verbose: true, logLevel: .debug)
                        print("pipe created")

                        // transcribe
                        let transcribeResult = await pipe!.transcribeWithResults(audioPaths: [selectedAudio?.absoluteString ?? ""])
                        var result = [Result<[TranscriptionResult], Swift.Error>]()
                        for res in transcribeResult {
                            result.append(res)

                            switch res {
                            case .success(let transcriptionResults):
                                print("Transcription Results: \(transcriptionResults)")
                            case .failure(let error):
                                print("Transcription Error: \(error.localizedDescription)")
                            }
                        }
                    } else {
                        print("Error while moving file.")
                    }
                case .failure(let failure):
                    print("Error: \(failure.localizedDescription)")
            }
    }

In the console I get this:

    File copied in 
    file:///Users/{myuser}/Library/Developer/CoreSimulator/Devices/BF68DAF2-55B5-43A2-B0B1-03969ACAB6A8/data/Containers/Data/Application/21A29C2D-BFB3-41E9-9821-3D464901F1A5/Documents/audio.mp3
