Native Gallery "Error returned from daemon: Error Domain=com.apple.accounts Code=7 "(null)""

The error in the title occurs every time, when I test my unity mobile application on Xcode.
if there’s anyone who is familiar with this error, would you give me some advice??

Unity version: 2019.2.9f

Xcode version: 11.5

Used Asset: Native Gallery

My device for test: iPhone SE

Websites I referred:[iOS: selecting image appears but path not complete (no file extension) #93][1]

[UnityNativeGallery][2]

[Native Gallery for Android & iOS (Open Source)][3]

Code of Native Gallery on C#

 private void PickImage(int maxSize)
    {
        NativeGallery.Permission permission = NativeGallery.GetImageFromGallery((path) =>
        {
            Debug.Log("Image path: " + path);
            if (path != null)
            {
                // Create Texture from selected image
                Texture2D texture = NativeGallery.LoadImageAtPath(path, maxSize);
                if (texture == null)
                {
                    Debug.Log("Couldn't load texture from " + path);
                    return;
                }

                testImg.texture = texture;
                imgPath = path;

            }
        }, "Select a PNG image", "image/png");

        Debug.Log("Permission result: " + permission);
    }

Entire log when Native gallery method is carried out.

In order to check whether native gallery properly works or not, I use this simple layout for my device test.
