Error in DownLoadHandlerFile

Unity Engine

Hello everyone!!!

I try to download an asset bundle from a web server because I need to save all the AssetBundles on my local PC. First of all, I save all the links of the asset bundles in a firebase, after I consult the firebase try to download the asset bundle with the following code:

    IEnumerator DownLoadAssetBundle(cars _car)
    {
        UnityWebRequest request = UnityWebRequest.Get(_car.ModelURL);

        request.downloadHandler = new DownloadHandlerFile(urlFolder);

        yield return request.SendWebRequest();

        if (request.result != UnityWebRequest.Result.Success)
        {
            Debug.Log(request.error);
        }
        else
        {
            Debug.Log("saved in " + urlFolder);
        }

    }

but when I try to test it, Unity gave me the following error:

ArgumentException: Failed to create file E:/Unity Projects/Firebase/Builds
UnityEngine.Networking.DownloadHandlerFile.InternalCreateVFS (System.String path, System.Boolean append) (at <22cd8f01dc1543789c8f26f4546673cc>:0)

UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

I close my antivirus (sometimes my antivirus gives me some issues), and y put the HTTPS in the link, but don’t solve the error. I don’t know what happens.

I hope someone lets me know where is the error.

thanks and regards

UPDATE

The issue was solved. But I have a new one. When I try to download it from the HTTP didn’t works, i can’t se the copy of the file, but when i try with the HTTPS appear the next issue:


Curl error 60: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_USER_ERROR1

UnityEngine.Debug:Log (object)
