Monster creator -unknown error with saving

The monster creator is having a few hiccups when it comes to doing its job, the main issue is when I make the monster and hint save it pops up with a red box that says an unknown error Happened and then when I try to close out of the monster sheet by tapping somewhere else it stays on the screen and I'm forced to reload the site by closing the tab and opening it up again

Steps to solve problem (my scenario)

Go to monster section

Hit create new monster

Press generate with ai

Let ai do its thing

Wait for picture

hit save monster

And the issue should pop up but on other times testing it I can get 3 or 5 monsters save before it breaks
