Anyone can suggest what need to done.
Thanks!

maybe someone can help if you share the script that you use.
From the little you shared it seems you’re using a variable with name error that doesn’t exist

I have share script. Please can someone suggest what’s wrong with my setup.

error in your fallback script is not defined.
