Plugin throws "Undefined index: originalsecret"

[jpkeisala]

I just downloaded empty Grav+admin and installed plugin via admin. After configuring Flickr API access I tried to add invidual photo or photo-set shortcode but I am getting error: "Undefined index: originalsecret" when trying to load the page.
Below is stack trace when trying to add [flickr-photoset id=xxxxxxx]
