Tried tracking this down but I think it may be quicker to ask for some assistance on this one...
This is the error I get, however I'm passing the string

however as you can see from the next screenshot, I'm the error string "disabled account" is being passed to the callback...

I can't really find documentation on exactly what is expected from the callback function and trying to debug it hasn't been very helpful either. Hopefully someone can shed some light...
The goal is to have a customized error message returned to the user, instead of "Something went wrong while parsing...". It would be much more helpful to let the user know that the Cloudinary (in this instance) account was a disabled account.
