Description

Firebase pod Firebase/MLModelDownloader crashing when I attempt to download model from firebase

Thread 17: "Task created in a session that has been invalidated"
An abort signal terminated the process. Such crashes often happen because of an uncaught exception or unrecoverable error or calling the abort() function.

function

func downloadFile(with url: URL,
                    progressHandler: @escaping (Int64, Int64) -> Void,
                    completion: @escaping (Result<FileDownloaderResponse, Error>) -> Void) {
    // TODO: Fail if download already in progress.
    self.completion = completion
    self.progressHandler = progressHandler
    let downloadTask = downloadSession.downloadTask(with: url)
    // Begin or resume model download.
    downloadTask.resume()
    self.downloadTask = downloadTask
  }

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @omokagbo, do you have a full stack trace of the issue? Also, I'm wondering if it's reproducible using this MLDownloader sample app.
