Error downloading redgifs: TypeError: can only concatenate str (not "NoneType") to str

[rostam-rakhsh]

I'm calling the command:

    cmd = f'gallery-dl {url} -d {save_path_dir}'
    sp.call(cmd,shell=True)

Where url is 'https://www.redgifs.com/watch/defenselessbaggyhellbender' and save_path_dir is 'Downloads/saved_reddit/' and I'm getting this issue. Same kind of issue with any other downloader I'm using for redgifs.

Verbose output below:
